Guys, I maybe wasn't clear enough. I am not looking for the LMTV to buy , I am looking for inspiration as to how to equip the box.
Spare parts... probably need to figure out how to carry at least one more spare tire. Don't forget the tools to use them, and you may not have slave power or air to work with.
If you are looking at going overseas, you need to figure out how to 'shrink' the shelter a bit probably, depends on where you're going and shipping requirements.
Foldable bunk beds, foldable table, toilet requirements, portable shower. Maybe a water tank and/or A/C unit on the roof or front of the box if it doesn't interfere with the spare. I'd look at addition of under the shelter stowage boxes plus an easier in/out method.
Google search terms... overland or overlanding rig might help. Are you looking for links to actual items? or just though processes?
