My blacksmith's truck is a 1972 Chevy Camper Special, C-20 Custom DeLuxe with 89K original miles. The Camper Special means it is really a 1 ton in sheep's clothing. 1 ton axle and leaf springs on a '72 mean C-30 in most cases
I have pulled a 7000# trailer load with little trouble. It also had a forged dragon with spread wings and a BarBie doll riding the on the shoulders as a hood ornament.
