Pulling a 5th wheel RV trailer with a 1/2 ton.

1978 Chevy Big-10 Silverado w/ a 1977 27ft Coachman. Don't remember the weight. Modern 5th wheels are built lighter for sure.
350 4 bolt main, Built Turbo 350, 14 bolt 3:73 ratchet locker, dual fuel tanks, H pipe duals

Pulled great. Sure miss that truck.
