I've been there. Chevy gas extended cab SRW. added Rancho Shocks, air bags it was a 2500 Silverado. Felt very uneasy with all the sway. Changed two years later to DRW Chevy 3500 crew cab long bed, diesel. Never been happier. Everything stock, no more sway and lots of power. Don't really feel like I'm hauling anything.Even pass cars going over Snoquamie Pass. Getting 12-14 MPGs. Camper 10 ft OKANAGAN about 3500 dry weight. A 3/4 ton GVW IS 9200# a 1 ton SRW is 9900 GVW while a DRW 1ton is 11400 GVW. I was always at 9900 to 10000 pounds loaded ready to go. Even had to not carry water just fill up at Campground. Now I carry water, and every thing including firewood no problem. DRW IS THE ONLY WAY TO GO. Come by a see my rig. I live in KENT. PM me if you want. Dennis
