Unimog have great off-road capabilities, but are less than ideal for highway cruising; and they are very expensive.
It seems that the Iveco Daily van and Cutaway chassis is a good middle ground, and has taken over where Mercedes Vario left off. The Iveco Daily is also body-on-frame and can be ordered with factory 4WD like the Vario. It’s just not quite as wide or heavy duty, but is far more modern and seems to make a great off-road camper, albeit smaller, based on popularity.
