You may already know this but the problem with a "run-of-the-mill" Chevy, GMC, Ford, or Ram 1/2 ton is payload. It's the Achilles heel of the towing experience. The factory rated "towing capacity" on any truck is pointless as one will reach the the payload limits way before anything else. Assuming 1500 lbs of payload on the typical GM 1/2 ton and 12-15% tongue weight of a 8000 lb "ready to camp" pull behind will net a reduction of 1000 to 1200 lbs of payload capacity. Subtract 100 lbs of hitch and one will have very marginal numbers remaining to accommodate humans, cargo, and refreshments in the TV.
I'd suggest limits of 6500 GVWR for a prospective trailer and a substational 4pt WDH with sway control like an Equal-i-zer.
