these trucks are truely amazing. I am a contract military heavy wheel mechanic and have worked on these exclusively up until last year. for what they are put through they are nearly bullet proof. the only problems that they have are normal wear and tear and the rare but deadly electrical problems. these trucks from the fmtv class are the one of the most electronically advanced trucks i have seen while working with the army. the civilian truck version is really cheap considering how much it costs to build them. also parts for them are some what hard to obtain due to the fact stewart and stevenson custom manufacture quite a percentage of the truck. but once you get past the cost, it would make one of the best expo vehicles in the heavier truck class in my opinion. if i had the opportunity to work with these things again, i would do it in a heartbeat.... by the way they drive awsome too, i had the opportunity to drive the 2 1/2 ton (lmtv) 5 ton (mtv), wrecker, cargo version, dump truck, bob tail, air drop version, van version also. :victory: awsome vehicles
