Mk48
I own its Marine Corps cousin... a Mk48 LVS. Its the same basically, save the articulation in the middle for the Mk48.
Mine is the Mk48/15a1 recovery unit with a crane and 60k A Frame on the back. You would NOT want one of these as an expedition camper.
Its uncomfortable, its hot, its EXTREMELY maintenance intensive (beyond belief) and its DRINKS, and I mean DRINKS fuel.
3.5 MPG best on road, not to mention its horrible habit of the infamous "death bounce" at speed, unless of course you have about 10 tons of weight on the back.
We use mine to maintain my tank collection... incredible vehicle but best left in Gov. hands unless you have a specific use that matches its skills.
