This would work great for you price seems a little high in the first on, look in the 3K range go for a pre-75 if you can (no catts) 350 SB (most mass produced engine on the planet) 2 fuel tanks, EMP proof, and
PARTS ARE CHEAP so you can buy spare parts. Plus it is cheap so if you ding the side up on a trail or other car, it's no big deal because it's not a 40K truck.
Good luck finding Unimog parts
I have a 1985 Chevy K20 3/4 ton 4x4 it is by no means fancy but it will get the job done any day of the week. like I said parts are cheap and plentiful. I lifted my 4" to be able to run 35" tires(have 32"on it now). I live in AZ I'm sure my truck will get me anywhere I need to get in the state. I bought this truck for the same reason you want one for. I have 4 people in my family and if we had to could fit into the cab(it's my hunting truck too)
I paid $1600 That leaves a ton of room for a camper extra parts and bug out gear
I can find campers ($1500-3000) for them and that adds to the whole STHF truck now you have a place to sleep, cook, shower, poop, 4-6 people could live out of one if you had to plus room for tools, guns, food, and the whole thing is cheap moble (4x4) and you would have plently of power with the V8
