There's a couple of trucks at the two auto dealers by the airport (on Vilas road). No idea on price, but one of them looked pretty decently built (solid front axle).
There's also a brown 60 at one that they wanted $2k for. The body looked in good shape, so I'm assuming the engine's blown up or something.
Didn't stop to look at any of them.
There's also a white 80 that's on North Pac....but that sucker is THRASHED. They want too much for it too ($4,500, if I were buying it I'd start at $1,500). Body is in good shape, interior is pretty torn up, front axle is probably completely shot (most likely needs new birfs, etc). Easily upwards of $2k to get it in decent condition again.
