Setting up an old truck/camper unit is the only thing that would make me sell my current rig, I think they so much cooler than laying down $60-100k on new stuff.
I love any make from the 70's down, but something in the 60's would be my pick.
that truck is in really nice condition, and is going to look sweet.
I will promise you won't be able to fuel up with out someone walking over to take a look at it.
