yes its has a 6.6L Turbo Diesel Duramax, quick as hell i would say 0-60 in 7.5 secs, not bad for a diesel; it gets up quick but after 50 or 60 it doesnt have as good gearing for high speeds. split rim with digital tire pressure system, but that thing ends up being annoying as hell b/c its not accurate, ends up beeping every 10 mins. i dont know what its goverened at but i know he had it upto 110. has that desert runner spare tire holder, swing arm. its automatic with aster switch, black out drive, stock 33's had a small lift but cant remember how high, still had fully functional GM interior as far as radio, ac, no power windows or locks though Military spec seats, but a hell of alot better than HMMWV's or any other previous m series, they are actually pretty comfortable. i can get part of the T.O. or for you Army guys the TM but i can only get one as of right now online, havent seen a paper manual yet. the front brush gaurd came stock like that with the chevy emblem cut out, rear bumper is metal as well and of course it comes painted in the OD Green CARC
