I've always Fancied a 101" FC Radio Body
Immediatly made me think of Terrängbil 11, or as its known globally, Volvo C303:
These are petrol driven, with a straight 6cyl Volvo B30, double
Zentih/Stromberg carbs, and a special high-torque cam. Very thirsty. Always 24V electrics. Of course completely lacking crumple zones. Weight-wise they're classed as "light truck" so can be driven on a common car license (unless you're military, then you need a special permit. Hell, you need a special permit to drive an ordinary civilian-type car in the military too.).
They're very, very good offroad; a standard issue model won the 1983 Paris-Dakar, light truck class. I'd originally wanted the aluminium body radio version, preferably converted to a Mercedes diesel, but now that I've got the necessary license and some sense of right proper vehicular class, I'm aiming for a Terrängbil 30:
It's a Scania 6-cyl truck diesel, automatic gearbox, all-wheel drive in off-road conditions, and over 80% civilian parts, still orderable from Scania. (TBH the same was true of the C303, at least engine-wise, but now that Volvo Cars has divested themselves of most legacy you have to look at specialists for most parts.) It can be equipped with a 10-person cab in the rear, and is probably the ultimate camper. Not legal for environmental reasons in cities, though.
