That Buick seen in the truck was 4100 lbs when those photos were taken-truck was great (currently moving a blown corvette around Australia these days) but the terrible anemic 366 ci gas engine was not. The 2 speed axle made it manageable, but barely. 6 mpg on the flat (3 at low speed WOT LOL) in the mountains. Had I kept it, it would have received a (8.1) 496 injected from a late model or better yet a diesel. Also the old hydraulic DRUM brakes were adequate at best.
here is a C30 version-the smaller trucks need A LOT of suspension and brake help!
