You can pick up a nice 1st gen (01-06 I think) Tundra, with 4.7 V8, crew cab, for like $8k around here. Probably not worth all the trouble fixing new rear end, and frame. But if it's just body mounts, that's easy.
But I'd Craigslist it, I had 2 buddies sell nice ones for around that price. Both really liked the trucks. One had to get a Landcruiser 100 to fit his second kid, and the other wanted a diesel.
