I went through this exact same exercise. 2009 Silverado 1500 5.3, HD towing package (adds trans cooler and gears - 10K towing cap) puling a 30' Keystone 30RIPR (36' hitch to spare) that is 6750 dry. I've never weighed it like some of the guys on here, but the wife takes everything we own, so I am guessing at least 8k loaded. The Silverado will pull it, and it will stop it, but it is NOT a good time driving. The front end floats despite the Blue Ox Sway Pro weight dist hitch. Like all over the place, and hold on when a semi passes you. You are going to get pushed, and then pulled into it. Its a rush the first time that happens. The truck can do it, but it doesnt like it. Its drops 2 gears on any decent hill - I live in SC, and have never pulled it in the mountains, only to the coast. Started pulling it with an F-250 6.7 and never looked back. TOTALLY different experience. Can cruise down the interstate at 70mph and pass semis with one hand on the wheel. I actually forget the thing is back there sometimes. I would get more truck, or get less camper.
