I am of the same opinion Clive all they have done is ruin the 80, it looks like a lot of work has gone into that conversion and one thing I noticed is that there is no provision for a spare wheel,
A 4x4 Mercedes Sprinter would make a good base vehicle sadly I am a closet Mercedes commercial vehicle fan as I did my apprenticeship on the L and V series trucks.
I found myself searching various websites the other day and found a pair of trucks that one of them could probably be made into a perfect over lander camper, I know
these very well and they have exceedingly basic wiring, the only solenoid is on the starter motor, the only relays are for the lights.
Fantastic (agricultural) and easy to maintain but getting rare I suspect.
