We've now got
4 HMMWV's
2 (maybe 3) 5 tons
1 or 2 LMTV's (Stewart & Stevenson)
and 1 MTV (Stewart & Stevenson)
All have been bought through Iron Planet/ Gov Planet (same site). Iron Planet does do a pretty good job with pictures and descriptions.
Military does a pretty good job keeping these rigs going. It is not uncommon to by a 5 ton with a <2 year old Cummins engine in it.
Word of warning, if you are comfortable working on and modifying vehicles then you'll have no issue. You can make non original parts work in most places. If you're not comfortable doing mods but can change parts, "original" parts can be expensive. If you're not comfortable doing much of any vehicle work, parts and labor are even more expensive.
In my oppinon the 5 tons and Stewart & Stevenson vehicle are the most bang for the buck. The HMMWV's have a cool factor, but they are a pain to drive, work on, get parts for, etc. 2.5 tons are almost all gone as far as GOV auctions go.
