Rawhide,
Before you plunk down the money on any LARGE truck, realize that parts (almost ALL of them) cost two to three times any part on a CUCV. And you WILL need Soldier B a lot more with any large truck when doing almost any kind of work.
As long as that's ok by you, go for it.
I started with a deuce. Great trucks. But for my purposes, I ended up with an M1028A2 dually and an M1009. I paid $6300 for the M1028A2 with 13k mi and $3000 for the M1009 with 13k mi. Both from GL.
Rarely can you just jog on down to OReilly or Napa and pick up parts for any of the large trucks. Not saying SOME of the large truck parts are not at those stores, just not many. CUCV's parts are at those stores, mainly for their civi counterparts for sure, but they are available.
just something to think about - big trucks are kewl and way fun to run - but drop $200+ for diesel for a day's worth of fun (one fill up on a deuce) and the M1008 getting 12 -15 mpg looks pretty good - the M1009 getting 18 - 20 mpg looks even better.
but hey, I'm ... uh... thrifty... er ... a scrounger... OH CRABAPPLES, I'm a cheap sob sometimes... OK?? Being retired with no large income I make do...
