Truck camper like some of the ones in that thread. Some have mounted a trailer on the truck frame. At the moment I'm toying with the idea of a Fuso FG with a utility body and a pickup camper, perhaps one that pops up. The utility body would give tons of storage.
I'd considered a Unimog but they are not a very good on-highway vehicle. I'm looking for something capable of very rough roads and on-highway, not necessarily something like a Unimog or Tatra or Man which really come into their own completely off road.
