I think the AWD makes a lot of sense for winter roads and the occasional sand/gravel. Our transit is just a RWD but with great AT tires is actually very impressive how far you can get. So far our limiting factor was ground clearance with the rear differential. Since we owned the transit, we have taken it to a lot of places we took the 4x4 crew cab sprinter. Places where I needed 4x4 in Benz, the transit just rolls through. Therefore I believe the RWD transit is pretty capable.
what are your thoughts on having the cab-over open to the cab i.e. cutting the roof of cab out? did you consider this? what may it have entailed as far as structure etc?
nice build. i love the simplicity. simplicity is was too underrated in thr RV industry. as you said "flashy" sells. i know too many people that dont use or havent fixed RV features because of failure or fear of failure.
