I have a 2021 chevy silverado Custom1500 2.7liter 4x4 6.5ft bed. I have airlift bags and 20in D rated General atz's tires. Camper is a 1998 Northstar TC800 weighing in at about 1350# dry. I have just shy of a 2000# payload with this setup. I will hover around that for the most part and wont go over that...much. Mostly myself and a couple dogs and gear. Food will probably put me over...lol. I havent loaded it on this truck yet and plan on doing it soon. Just have to figure out how to get the stake pocket brophys mounted first. I know I know torque lift is the way to go but after the tires and bags my budget is brophys!
