There's really no economical fix for the truck. The frame really isn't as rusty as the picture shows, but it's not great either. We thought about trying to plate the frame so he could still drive it, but the hit was directly to the wheel and it looks to me like the frame is bent.
The cab is buckled in the back by the window too, so there's no coming back for the truck.
It's a shame too.... He got the truck from my brother inlaw last year who had the truck for quite a few years. You don't see a lot of older trucks around here that are in decent condition. The truck got new rear leaf springs last fall and a new clutch and slave cylinder this past spring. 4wd, straight six, 5 spd.
