First up let me say I love my 2008 D40 ST-X, unfortunately I may have to scrap it. I have bent the chassis for the second time and despite being under warranty Nissan are not interested, my insurance company will straighten the chassis again but will not allow reinforcement of the problem area.... result I may have to scrap the thing as IT IS UNSAFE. yes I have ARB upgraded suspension and Airbag man assistors but they (despite claims to the contrary) are not the problem Although they do void the Nissan warranty. The problem is that Nissan have put a a 2.5mm steel box section chassis on a mid size 4WD ute, the weakest chassis of any 4WD ute I have seen in Aust. Seriously have a look at any other ute even other Nissan Utes and they have much stronger chassis. 2.5mm steel rectangular section is nowhere near strong enough to handle the ute let alone hanging an off road camper off it and tackling anything other than bitumen (no potholes of course) is not an option......very surprised this one is allowed on Australian roads such is this critical design weakness.
