From the mid-1990’s the Family of Medium Tactical Vehicle (FMTV) was utilized by the US Military in a variety of forms. It came in 2.5 ton and 5 ton configurations and served as radio station, troop transporter, crane, off-road semi, and general cargo hauler. More info is available on the wiki.
Many of these units are now in public hands and can be a suitable platform for an overland adventure vehicle. They can be built into the ultimate off-road motorhome albeit in a loud, heavy, brutish package.

As of mid-2017 we don’t currently own one. This page is an effort to collect pre-purchase research into a single, easily accessible location. We hope this might be useful in your own FMTV research.
