It took a lot of thought to commit to selling our 80 Series Land Cruiser, and to move to another vehicle. I pondered for weeks, made multiple spreadsheets, looked online at every possible option I had, and then made the choice; we’d sell our Land Cruiser and buy an Isuzu Dmax.
If you want to know exactly why we traded up, have a read of this: Swapping from an 80 series Land Cruiser to an Isuzu Dmax.
The idea was simple; to build it into a 4WD that would tour Australia in relative comfort, capability, acceptable cost and that would work well to camp out of. When travelling, we tow a
Soft Floor Camper Trailer (not anymore!) Lifestyle Reconn R2 Hypercamper.
On top of that, it had to double as a daily family vehicle for around town, or the finances just wouldn’t balance.
I spent many, many hours planning, designing, building and installing various parts of the vehicle that you see today, and as of now, am very happy with it. It had to be ready to explore the 70 reasons you need to travel WA.
The vehicle is a 2016 Isuzu Dmax SX model dual cab, running the 3 litre turbo diesel motor that has been around for many years. It’s the base model Dmax, with vinyl interior and no fancy chrome bits like the other models have; exactly what I wanted.
I bought it it up from Victoria, and had it trucked over as the only other SX or LSM model Dmax with the non DPF motor that was for sale was ridiculously expensive in Perth.
This Dmax is the MY15.5 model; the last of the vehicles without the Diesel Particulate Filter (DPF). This, in turn means it doesn’t have the 6 speed automatic gearbox, and the slightly more powerful variant motor. It’s also plain, boring old white, for a good reason – What colour 4WD is best?
If you are looking for an Isuzu Dmax Touring Setup, this post covers the entire build in detail.
What did it cost?
A build like this doesn’t come cheap, but we’ve documented every part used, and how much it cost. You can find the full post here – Dmax build cost.
3 year review
We’ve now had our Dmax for 3 years, and have done a full review, which you can read here; Isuzu Dmax review after 3 years. We’ve had a few issues, but nothing major so far and we are very pleased with it. If you were looking for Dmax problems, there are a couple of more well known items but overall they are very solid!
Non DPF model
I specifically hunted down a pre DPF Dmax, and recommend avoiding them across all makes and models if possible as they are hugely problematic things that are ‘good’ for the environment and nothing else. They are fraught with problems, expensive to repair and a nightmare, in general.
I will quickly point out that at this moment the Isuzu DPF’s seem to be relatively trouble free, perhaps because they have been running them in their trucks for many years. That said, they are in no way proven, and until I see hundreds of them with over 250 – 300 thousand kilometres on the clock I can’t see how anyone can say they are reliable. This is especially the case for Dmax’s that are used for short trips around town, as this is exactly what a DPF does not like.
I expect a lot bit of trouble in the future for people that have vehicles with DPF’s. However, maybe they will be fine – like lots of technological advancements that just require some time to get used to. Time will tell.
The rest of the gear
I’ll start from front to back, running you through all of the gear, and giving you as much information as I possibly can.
AFN Bull Bar
Bull bars have been fairly plain for some time, and one day I stumbled across the AFN Bar, which is wildly different. Now, looks alone would never have convinced me to get one, but they are built in Portugal, the business is used for military products, they are light weight, strong and competitive in price.
One of the big selling points for me was the distance that they stuck out, as I knew things were going to be very tight in the garage, and also it reduces the stress on the front end. I have seen a few Isuzu Dmax’s with cracked inner guards, which some people claim comes from heavy bar work sticking too far forward.
The bar was a nightmare to install, and there are a few engineering areas where it could be improved. However, it has rated attachments for recovering off, its fairly well built and does the above things I mentioned. I’d get one again. You can read my full review here – AFN Bull Bar review
Runva XP11 Premium Winch
Runva has gained a great reputation for a cheap but good quality winch for the front of your 4WD. They are not the cheapest out there anymore, but they are well known and several years ago would have been the only ‘cheap’ but decent quality winch on the market.
I don’t use winches that often, but we do a lot of solo travel and its cheap insurance that I wasn’t going to do without.
Bushskinz Bash plates
One thing I was very concerned about with the Dmax was the lack of clearance underneath, and the number of sensitive things hanging down low. One rock to the wrong thing under there and you could be up for mega money, not to mention a difficult extraction.
I looked at all the brands; Boos, AFN, Custom Off road, ARB, TJM etc etc. Bushskinz were helpful, I could see it would marry to the AFN bar OK and they were reasonable price, so I purchased a set of 3.
These cover the radiator, sump and automatic transmission. The only place that makes transfer case bash plates are AFN, and they are about $1700 for the set of 3. To be fair, they are 6mm aluminium, and are far more work to make than anything else I’ve seen on the market. If money was no object I’d have gotten them, although aluminium does have a tenancy to gall, or stick to rocks as it slides over them.
The bushskinz ones are heavy; about 45kg. They are quite easy to install and remove, and have a couple of access points as you’d want. If you have any low hanging bits on your 4WD, Underbody protection is worth fitting.
HPD Catch Can
Catch can’s are an absolute must on any modern 4WD. You can read more about it here – Is a Catch can important on a modern turbo diesel?
EDIT #2: The Provent 200 is far more effective
I ran the HPD Catch Can for 34,000km, then put a Provent 200 on for 5625km, and the difference in oil collection ability is absolutely astounding. You can read the full report here; Provent vs HPD Catch Cans.
EDIT: I am removing my HPD catch can
After nearly 30,000km of testing, and an independent study done by Curtin University the billet aluminium catch can is being removed. Lets just say there are much better performing catch cans out there. Want to know more? Read this – Why I’m removing my HPD Catch Can.
The two most common catch cans installed on Isuzu Dmax’s are HPD, or Provent. The latter has been around for a long time, make quality gear and are proven to work very well. They have a lot of copies on the market though, so get the right one. They also have a few things about them I wasn’t completely sold on – little storage for oil collection, outlets that allow oil to spill out when on angles, a filter which removes most of the oil (which is great) but also puts more pressure on your motor (think rear main seal) and the filter it needs replacing every 40 – 70,000km.
Either way, I opted for the shiny billet aluminium HPD catch can (not because of its looks!) which runs a set of stainless mesh on the inlet and outlet to make the oil particules stick and drop down. My gut feeling is it doesn’t work nearly as well as the Provent (more information coming out on this real soon!), but it has a few other benefits that I like – holds a decent quantity of oil, has inlets and outlets in clever positions, mounts up in a kit very well, doesn’t need any ongoing maintenance and has a dip stick to check the oil level.
Fuel Manager 30 micron Pre Fuel Filter
Modern turbo diesel motors are extremely sensitive to bad fuel. A bit of water, some algae or gunk and you can be in real trouble. You’ll find stacks of arguments online as to what filter systems are best, and whether to put them pre or post. For me, it was fairly simple; you can’t put anything after the factory Isuzu 5 micron filter without voiding your warranty, so before it went. 30 micron is not very fine, and I suspect not really the right size, but it will do for now. This is mainly to filter out any big bits along with water.
After 15,500km on our 3 month trip It had very little in the bowl, which is good.
Automatic Transmission Cooler (aftermarket)
After seeing some pretty consistent 90 and 100 degree temperatures, I decided it was time to install an Automatic Transmission Cooler. This was fairly cheap, and has made a big difference to the temperatures in our auto box.
The antenna I went with is an RFI CD5000. This is the same as what I had on the 80 series, and I love it. It’s big but not ridiculous. It’s black so minimal reflection and annoyance from it being on the front of the car, and its extremely well built.
Beyond that, it works brilliantly; I often have by far the best radio reception in our group.
Icom remote mount UHF
Our 80 had an Icom UHF, and I was very pleased with it. They are commercial grade, and built tough. The remote mount unit was only about $40 more, so I grabbed that. The actual radio is now mounted under the dash, with all of your controls and speakers on the actual hand piece. This also allows for the hand piece to be unplugged and put away from thieving eyes when the vehicle is being driven around town. When we head out on a trip, I can pull it out and plug it in.
Isuzu 16 x 7 Aluminium Rims
I’ve always run steel rims on my 4WD’s in the past. However, this time around, I was more conscious of weight, and quality aluminium rims are easily as strong if not stronger than steel ones (just impossible to repair if you do damage them!).
Unsprung weight is very important for corrugations as it makes your suspension work much harder. I purchased 8 second hand Isuzu rims off Gumtree for about $400. These are positive 33mm (the same as the OEM steel ones), and have been fitted to our camper trailer as well, so we have matching tyres and rims.
Toyo AT 2 all terrain tyres in 265/75/16
I did a lot of research into tyres. I found out you could legally run 265/75/16’s on the SX Dmax, and accepted the costs that bigger tyres would bring on the vehicle. If you want more information, have a read of this – Fitting Bigger Tyres to your 4WD, and for those specifically looking at the Dmax this – Tyre size; you can go 50mm above the largest tyre in your model range.
I’ve always had mud terrain tyres, and was nearly going to commit to another set, but for the 10% of situations where muddies would be better for me, I succumbed and went with all terrains. Eventually, it came down to two tyres – the BFG K02 all terrains for $285 a tyre, or the Toyo AT 2 tyres for $239 a tyre. Remembering I was buying 8 (3 for the camper trailer), so there was some buying power.
The BFG’s are a very, very popular tyre. That said, I found a heap of people who weren’t happy with them, and it did put me off. Instead, the Toyo’s had an amazing reputation, with very few people who had issues. Great grip in all situations, good puncture resistance and great wear. Perhaps its just more people own BFG’s and therefore a small portion of them complain, I don’t know. That said, Japanese tyres are becoming very well reputed when compared to anything coming out of the USA.
Eventually, I committed to the Toyo’s, and to date have been very pleased with them (although the rear tyres did wear a LOT over our 3 month trip!). Keen to know how they’ve gone over 20,000km? Check this out – Toyo Open Country AT2 Review.
Old man Emu suspension and GVM Upgrade
In the planning stages, I had always banked on getting Old man Emu Suspension. I’ve run it before and been fairly happy with it. ARB has a massive backing of suppliers and its well known for being good gear.
I will say that if you are really pushing your 4WD on nasty corrugations then you need to go remote reservoir shocks, but for our purpose, the normal nitro chargers were fine.
The curve ball for me, was finding out the weight of our Dmax and realising I’d need to get a GVM upgrade. I took the vehicle to the local tip one afternoon, ,and with very little gear in it the weight was nearly 2500kg. That didn’t leave much for all of the gear, and despite trying to reduce weight I knew I’d be over with the tow ball weight of the camper.
I did a heap of research into GVM Upgrades. It eventually came down to Pedders or ARB, and I went with the latter. It’s now got a maximum GVM of 3220kg, or 270kg above the original. The front springs are the heaviest you can get, and the rears are 600kg constant load. Given our vehicle stays loaded most of the time, its worked out just great.
If you want to know more about what our Dmax carries, and what it weighs have a read of this – Isuzu Dmax 4WD Touring weight.
Diff drop kit
Another curve ball was realising a few days prior to leaving for 3 months that the CV angles weren’t great. A quick call into Coastal 4×4 and I had a Roadsafe diff drop kit, which has reduced the CV angles considerably. If you are lifting your Dmax more than 30mm, this is a very important modification you should consider fitting. You can read more about that here – Dmax Diff Drop.
I reckon you are mad heading bush with a modern 4WD and no way of diagnosing any faults that the computer throws up. You can buy the Torque Pro app and a bluetooth adaptor for very cheap, or if you want something more permanent a scan gauge or an ultra gauge.
I stumbled across the latter in my research, and basically concluded they did the same as the scan gauge but with a much, much nicer display, so went ahead and ordered one. This thing has been unreal. It’s mounted to the windscreen via a suction mount, and can read about 150 different sensors that the ECU supplies.
I primarily use it for engine temperature, boost, automatic transmission temperature (a big one), voltage and engine load. I wouldn’t go anywhere without one now; its been fantastic for seeing how your vehicle is coping, and I have used it to clear a fault after some electrical work was done that you’d be driving around in limp mode without.
Redarc Tow Pro Elite
Our camper trailer is over 750kg, and has electric brakes, and therefore the tow vehicle needs a way of controlling it. The Redarc Tow Pro Elite is a no brainer – they are by far the most commonly fitted. They are fantastic quality, easy to use and really simple and tidy.
Stedi ST4K 42 inch LED Light Bar
With all of the work going on, I knew I’d kill myself if I hit a big kangaroo on the first day of our big trip up north, so a few hundred bucks on some decent lighting was an obvious investment.
Given the WA road rules had finally caught up with the rest of the country in allowing light bars on top of canopies, and that pricing of decent units had come down a lot, it was a no brainer. Stedi are another cheaper imported product that has a great reputation (and a 5 year warranty) for both quality and performance.
I had to mount it up fairly high in order to clear the roof of the Dmax (as its mounted so far back), but this thing is absolutely unreal. The light is substantially more targeted than I expected, and will do 1 lux at 1000 metres. No idea what that really means, but its bright and fantastic to drive with at night.
These come with the harnesses to make installation pretty easy, and I purchased an anti theft kit as well. These are just two security nuts that screw on and you need a special tool to remove them. Hopefully enough to put most thieves off.
I’ve written a full review, including night photos of it here – Stedi ST4K 42 inch LED Light Bar Review.
Safari have been making raised intakes for years now, and they make quality gear. You can get much cheaper ones off eBay, but is it worth the risk? This helps to keep the air filter clean when on dusty roads and the motor safe in water.
200W fixed solar panel
When I bought the canopy, it had a 120W solar panel mounted on top. Given the 100W one on the cruiser only just kept up, I figured I’d swap it for a bigger one. A 200W mono panel was purchased from Low Energy Developments, and mounted on the two rails of the canopy.
I did spend some time bracing the panel, as it flexed quite a bit along the length of it (due to only two mounting rails), and also the glass moved up and down a lot over the width. I used some special rubber (Linatex) and aluminium angle to stop it from flexing, with a length of 30mm x 3mm flat bar down either side to stop it bending.
I’ve gone with a fixed solar panel that is oversize, so I never have to play with moving panels around. There are some pro’s and cons to fixed vs portable solar panels, so decide for yourself.
Bull Motor Bodies Aluminium Gull Wing Canopy
Dual cabs with normal fibreglass canopies (even if they have windoors) really frustrate me for touring. They are heavy, take up so much room and make access a right pain in the behind.
I knew I wanted an aluminium gull wing canopy, but wasn’t prepared to pay the exorbitant prices that they cost new. Eventually I found a Bull Motor Bodies canopy for sale off an extra cab Hilux, running a short 450mm tray on the rear. I picked it up for $3800, cut the tray off the back and moved the bumper forward, making it 1700mm long.
These canopies are fantastic, and at $12k new a few years ago it was a bargain and a half. It came with a 50L water tank and electric pump, 2500W inverter (why you’d want one that big I’ll never know), central locking, shelving, LED lighting, solar regulator, 120W solar panel, roof racks, underbody toolboxes (which I didn’t fit) and about as good as it gets in terms of quality of build.
This particular unit is a chassis mount job, so the tub was removed and this bolts directly to the chassis. If you are looking to get a Ute Canopy, there are lots of things to think about. You can read all about it here; Buying a 4WD Ute Canopy; the Ultimate Guide.
Custom fridge slide and drawer system
There was nothing on the market that did what I wanted it to, and enjoying the occasional wood project I decided to build my own drawer system. You can read about this here – Fitting out our Dmax Gull Wing Canopy.
Two 1000mm drawer extensions were left over from a previous project, so they were used as the fridge slide. 6 Oates Drawers from Bunnings were purchased to hold our goods, and two sheets of 12mm marine ply. I propped the whole unit up 38mm with some pine, and many hours later it was complete. Fridge slide, table, plastic drawers and lots of storage.
I mounted a number of t nuts and eye bolts to the top to tie gear down as well.
Along with the help of a great Perth mobile auto electrician, I knocked up a box to house the electrical gear. This has numerous switches, two cigarette outlets, two usb outlets and 3 anderson outlets. The Projecta dual battery monitor was installed to keep an eye on the battery voltage.
I wanted something simple, economical and functional. I don’t need battery monitoring systems and fancy 240V chargers. They are lovely, and very cool, but a a couple of grand saved is better put towards fuel money.
Projecta DCDC Battery charger
The 25 amp Projecta IDC25 was also installed in the above electrical box. This takes charge from the cranking battery, and regulates the voltage to charge the battery to maximum. It also has a solar input, which is where the panel connects to. I’m not entirely sold on the need for DCDC battery chargers, but it kills two birds with one stone.
I30 Solar regulator
The canopy came with a 30 amp PWM regulator already mounted, which I’ve chosen to keep and wire up should the DCDC give me any issues. Stephen has wired it so I can swap an anderson plug over and run the 200W panel through the 30 amp regulator and still charge the battery should something go wrong.
55L Evakool Fridge and or Freezer
We’ve had a good run from the yellow , so purchased another one just before the 80 series was sold. This has been mounted on the fridge slide, and does a great job of keeping everything nice and cold!
150 Ah Bosch Deep Cycle Battery
Our 80 series ran two batteries, and the normal SB12 redarc isolator, which allows you to use some power from the cranking battery before shutting off.
That system kept up, but was touch and go a few times, so I decided to go even bigger on this system. A 150 amp hour Bosch battery was picked up from Goodchild enterprises for about $400, and with some careful metal work two brackets were made up to keep it in position. This weighs 45kg, and has been put as far forward in the canopy as possible.
50L water tank and electric pump
The water tank is also located as far forward under the canopy as possible, and runs to a small 3.5 Litres a minute water pump and then out the back of the bumper through a tap. Having running water when you are camping is magic. Our camper trailer also has water tanks, but a day down at the beach or cleaning dirty hands when on the road is made very easy by having water on board.
Isuzu tow bar, charging anderson plug and reversing camera
The Dmax came with a genuine tow bar (which I detest as it hangs very low). I knocked up a bracket to move the trailer plug out of harms way (why they mount them under tow bars has be baffled), and had an anderson plug installed to charge the camper trailer while we are driving.
The factory Isuzu reversing camera has been great, and is an absolute must if you have a solid canopy on the back. You’d be completely blind reversing without it.
It’s a no brainer to fit diff breathers to your 4WD. Water will do nasty damage to anything it gets into, and crossing water with differentials that are hot does exactly that.
I bought some 1/4” fuel hose, and replaced the existing breather with new hose right from the rear diff to the back of the firewall in the engine bay, with an air silencer on the end to allow it to breath and keep the dust out.
Bigger cranking battery
After buying the Runva winch, I read the instructions which clearly identified the CCA of the factory battery wasn’t enough for the winch, and if you used it the winch warranty would be void. Not a modification I’d planned on doing so soon, but I removed the factory battery and replaced it with an N70 size Amaron cranking battery with around 750 CCA.
Ute’s are great things, but you’ve got to keep them relatively modular to make use of it all. I picked up a second hand Pelican case to keep my recovery gear, some spares, compressor and other bits and pieces in. It’s fantastic, and if its annoying me I can just remove it.
Interior light upgrade
You can never have too much light inside your car late at night, when you are trying to find something. I bought a Narva LED to replace the festoon one, which is an improvement, but not as much as I’d like, and its starting to flicker, so needs replacing with something better.
No engine modifications
Now, you’ve probably noticed I haven’t done anything in the engine bay, except for the catch can and pre fuel filter. The reason is simple; the motor is reliable, economical and does what I need it to without mucking about.
I’d love a bit more power, but I don’t want to sacrifice any reliability in order to get it. At least while the Isuzu warranty is in place there will be no modifications done. Perhaps a remap or tune may be on the cards later on, but not in the near future.
Other things to finish off
The rear drawer system needs some tidying up. I’m not sure If I’ll carpet it, but it does need some stainless sheet, or laminex on the working side of the table. The battery should really be covered so nothing can touch the terminals and the canopy could definetly do with some more lighting.
I might install a couple of work lights to the rear/sides of the vehicle too, as these are always useful.
We also want to ditch the factory head unit and replace it with something that will run Android. Having a fixed mapping system in your dash is truly epic.
Done and dusted
Well, the thought process and build took a lot of time and effort, but we now have a 4WD that is great. It’s not perfect, and a nice 79 series Land Cruiser would have been an option too, but at nearly double the cost it wasn’t even looked at.
