Isuzu DMax purchase

I follow exactly what your saying in regards to a GVM upgrade, springs and shocks only in an upgrade that may cause problems down the track.
Can you give a bit more info on the slim line fuel tank you have please.
William

William.
Don't get me wrong. I endorse the fitting of a bit more clearance, usually provided by improving the suspension. A more supple suspension which holds chassis height at a higher level will provide more suspension UP travel to absorb road conditions without bottoming, which is likely with the stock suspension. The shocks have to have greater ability to absorb porpoising action, ie, good front shocks and the rears will have to have more ability to absorb the van weight which is transferred to the rear axle and springs in undulating conditions., like dips. The better suspension should have the ability to hold higher and not cause excess component loading. With loads to the max, which isn't wise anyway, the stress on all vehicle areas is increased. If the std suspension crashes to the chassis and doesn't provide good control of steering and braking then it isn't great. I fitted Bilsteins to mine at 5000km from new, OE was hopeless to the extreme. Costly but Koni shocks will last and provide good mass control.

My slim 50L tank is simply a suitable sized petrol tank RED from one of the manufacturers. Any Hydrocarbon suitable tank is same but different colour. The Poly is the same. Just don't fit it in a confined space as once they are filled with a Hydrocarbon fuel they grow, once only, about 2% in all directions and may be hard to remove later. ie clearance to expand. At the base of mine I fitted a hose to a ball tap and then a Donaldson 11 micron filter with a sump for water collection, if any, and an OLD Commodore inline fuel pump to transfer fuel via a length of fuel hose to filler neck. Power for pump from a ciggy lead to a port in the tub. Pump mounted on an aluminium sheet saddle over the tank top . Just slides on. Hope this gives you some options.

John, that might be the case for your Nissan but……

From the factory all Isuzu D Max have a 3500 kg GMV as standard.

Stephen, I was commenting on the paragraph about getting a GVM upgrade, "the GVM upgrade was just to future proof the vehicle in case we purchase another van in the future."

John is correct. In my case I did the GVM upgrade because I found by the time I filled the car with tools, fuel, fridges, bikes etc, I did not have the capacity to take my wife and dogs, I could only add another 20kg after I was in the car. The GVM upgrade did nothing to the GCM but did allow me to add another 270kg to the cars payload so dogs and wife could come with me ;=))

My final weights fully loaded with the 2,500kg van meant I was 500kg short of the maximum GCM of 5,950kg GCM hence my earlier comment of 2,500kg as a good weight for a van.

GVM upgrade does NOT alter the GCM but does allow the car to carry more payload.

The GVM upgrade that was done on my car was done through the dealer and was part of the initial purchase. The dealer actually included the details back to Isuzu to ensure that it was included in the car warranty. If your dealer is not allowing the upgrade, it is time to find a new dealer who will cover it for warranty.

Hi Dunc,
Thanks for the heads up about the bullbar, I have confirmed this morning that they do not have recovery points.
I have priced the ARB Summit bar.
What TJM bar did you go with?
William

The Outback. Only annoyance if you can call it that is that the aerial mounting point is not further out on the bar. the accessory mounting points in my mind are a bit too centric on the bar, something I didn't notice until I had the UHF aerial mounted.

William

If you don’t get a bull bar….I don’t have one, there is a rated recovery point on the front on the D Max. Many say this is not correct, but Isuzu say it is rated.
