When in HS, 1976, friends Dad had a C30 pickup truck. Not C10 or C20, but C30. It was huge. He used it to pull a 5th wheel cattle trailer. It had 7/8 ton running gear which was as big as he could get without going to dual wheels in the rear. It looked like a regular pickup, except it was large enough His dad, mom, sister, him, and me could all sit on the bench seat an it was not crowded.
After college I had this...
4 inch suspension lift 34" tires. Went off roading all the time in it.
Dirt, mud, snow, trail blazing though the woods, fun.
