It is my feeling right now (might change in the next week or two) that your truck if far better suited for an "adventure camper" than the FMTV due to your truck having higher highway speeds, and open frame space up to the back of the cab, more open space for saddle attachments.
John, what is the top speed of your truck?
I honestly doubt that very many "sane" people would take an expensive camper into places that needed the all-terrain capability of a FMTV... but then again, there are plenty of people out there with more dollars the sense.
