[POWERSTROKE]

Wow, that truck looks in really good shape for being 57 years old! Does it run? 4 spd Trans and 2 speed axle?
I hope it's got at least a 351 Cid engine, 26,000# is WAY too much for a 305. I used to drive Chevy C65's with 366 Big blocks, 4 bbl carb, and 5+2 loaded to 30,000# gross and they struggled to get up to speed and hold it.
