Do you really understand what you're getting into ? Don't misunderstand, a Duece & a half is a great truck but you pretty much need to be a diesel heavy mechanic to work on it, either that or you need to have deep pockets (*really* deep pockets) because you'll need a *whole* new set of heavy tools to do anything with it. A 1/2" breaker bar might open the glove box but that's it. Unless you're a diesel mechanic you don't have a single tool you can work on that rig with and a truck like that is a completely different animal, there's a fairly long & steep learning curve. 2.5 ton axles are nice and sure we all like planetary differentials & pinion brakes but is it really practical in anything less than a full-blown monster truck or Ultimate Unbreakable trail machine ? Do yourself a favor and just look into what it's going to cost you to fab up 4 rims to mate standard 40" tires to those axles, you're not going to do all that work and just run the hard rubber military pizza-cutters are you ? Because those are the only tires that you'll fit onto the stock rims and trust me, Alcoa, Coddington & Craiger don't make rims for a Duece (just TRY finding spinners for one of those). Even if you keep the truck intact instead of hacking it up, the very first time something breaks you're going to spend more fixing it then you did to buy the truck.
They're great trucks, I love them and so do a lot of other guys, it's just that you should have a good idea of what you're getting into before you take on a project like this because that's probably how your buddy came to own the Duece in the first place <grin>. If you're looking at it as a long-term project and you understand up front that you're going to be investing quite a bit in factory/military manuals and spending enough on tools to buy yourself an Expedition that's cool. I applaud & envy you because I sure would like to have one myself. It's just that I enjoy being allowed to sleep with my wife even more and I know for sure it would be one or the other if I brought one of those home. Grab it if you want it, $1000 is a killer price if it runs & drives but just know what you're getting into.
