Thanks for clearing that up... I don't think it is a separate chassis unfortunately. I think they were designed as MPV's and light commercial vans. This one was converted from an MPV off the production line.
But yea.. Having the mighty Hilux 2.8 engine in it was a massive selling point for me!
As far as I can see the only disadvantages to it are, its automatic
the low ground clearance and the roof clearance (nearly 3m!). Though being tall was a must as I'm 6"3 and plan to be on the road for a year + so don't want to live like a hermit!
And with only 40k miles on it i hope the transmission will hold out for another 20-30k for this trip!
Back to tyres... Would it make any sense to buy them in Turkey, to do the europe on the ones i have, then pimp up before hitting the rough roads??
