We have the 2008 holden Rodeo that is the identical DMax

We added new suspension as the standard is way to soft and sloppy and put in a DP chip + a few other mods and it is a really good unit, we have not picked up our van yet but we plan to tow a 19ft evernew once it is built.

I have one...very happy so far. 2009 Sx dual cab, 4x4, canopy,bull bar etc.
35 mpg most tank fulls, 28 mpg half towing half solo. 5.8 m poptop van.
No problems so far but still only 3600kms so a bit soon to tell.
Tows well and is quite comfortable considering it is a commercial vehicle and base model.
Have no hesitation recommending the vehicle. Only point I would raise is that it is not as capable off road as my previous GU Patrol or 80 series were, but I am not full on offroading now so suits our purpose.
Oh the gear change is a bit average ...rubbery feel but you get used to it.
Regards Alan.

Use search , there are other posts on the Dmax.

We picked up our new D-max last week, we havn't towed our van with it yet but very happy with fit and finish.
Quite comfy for a work vehicle, we got the auto and are very happy with it - smooth changes and good ratio's.
as stated above, we will be doing some thing with the suspension, but would do that with just about any vehicle.
Could do with a bit better bottom end power, but that could be because its auto, a chip upgrade will fix that.
All up they seem to have a pretty good rep and Isuzu have been building reliable trucks for years.
Best of luck with what ever you choose.

Regards, keith

Good one Turk

I had my first problem last week. The auto trans and MIL lights came on for no reason at all. Also found that I couldn't shift the auto trans lever from park without depressing the lock device. Called the RACQ and the guy couldn't find anything wrong. Drove it to the workshop in town and they reset the computer (a half day job !!) and said everything was OK. Time will tell.

3700km and climbing slowly LOL.

G'day Turk,

We have a new auto LSU D-Max Crew Cab only 3,000 klms on it so far, have not towed yet but it was the only one in it's category that tows 3 ton with a auto gearbox. Be aware they are not the same as a Colorado, D-Max has DOHC with chain drive and 16 valves, Colorado has SOHC with belt drive and only 8 valves, from what I understand there are subtle differences throughout the whole vehicle. So if you want a real Isuzu buy the D-Max, it also has one more cross member on the ladder chassis then any other vehicle in it's category. The inside finish/fit out leaves a lot to be desired but we bought it for the specifications and reliability. We intend travelling around Australia towing a smaller van. I don't know where you live but don't be afraid to get a price from a smaller country dealer, my first price was from the Sunshine Coast dealer (I live near Gympie) then I rang the Bundaberg dealer (talk to Arthur) and saved $2,500 instantly.

All the best

"D-Max has DOHC with chain drive and 16 valves, Colorado has SOHC with belt drive and only 8 valves"

Where did you get this crap from, I hope not from a disohnest dealer - I thought this had been sorted out eons ago - RODEO RA7/8, COLORADO & D-MAX ALL HAVE THE 4JJ1 TWIN CAM 16 VALVE DIESEL MOTOR

Well Mal,

I suggest you do your research before you accuse someone of posting 'crap', below is a portion of the information found on the CarShowroom Website. There is no mention of DOHC's because it does not have them!!

The Holden website does not mention any of the below specs re their 3.0 lt Diesel in the Colorado because they know it is not the same as the Isuzu engine.

If you were to research first this then allows you to post CORRECT INFORMATION as I did, as opposed to the CRAP you have posted. By the way 'disohnest' is spelt DISHONEST.

I have a RA7 Rodeo with the 4jj1 engine and 2 mates who own Colorado's, 1 of whom is a mechanic and he too is a bit over this continual misinformation originally started after an incorrect Holden sales brochure which some Isuzu dealers took advantage of. I personally was told the pushrod story by an Isuzu salesman and also at a later date another Isuzu salesman admitted to me that some funny business did go on.

G'day Turk,
We bought an LS-U D-Max auto a month ago and I am very happy with it, we are going to tow a 5th wheeler with it next year so I want to get it run in before then. Got a great deal from Blue Ribbon Motors at Yamanto, very friendly and helpful. I don't think you can go wrong with a D-Max.
