Just a bit of a flag, and I'll mention it on Pros as well, but I'm selling my Navara within the next week or so.
When I get some more information available (photos etc.), I'll stick it on here.
In the meantime, it is roughly described as having a SnugTop, Thule roof rack and aluminium pole carrier.
Might be available with 460l stainless steel water tank, custom built, baffled, dual sight glasses, dual outlets, vent, filler, battery compartment, varistream etc. But the price for that will have to be considered separately from the truck. NOT AVAILABLE UNLESS PALM GREASED WITH CONSIDERABLE AMOUNTS OF MONEY. If you want a cheap system installed, then buy a cheap system.
Later...
