ooooowwweeeeeee. A truck in that condition with 70K miles which most of those miles were probably abused. Pass. It doesn have an 8.5L though...that's rare!
Your looking at a good $5-10k to get all new tires, rim, power steering, tail gate, cladding, body panels, front bumper, paintjob and misc. parts. Plus it looks like it took a side hit so could be unknow damage to frame or underneath
