My camper is light. Way too light for the 2500. But it tows a world better then the 2012 sierra 1500 i had with tow package. The sierra had no power up steep grades,l and i think the variable cylinder thing hampered the power. The 2500 can pass things. Its huge inside and out. Hitch camera is an upgrade for me. I get 12 mph towing like 5500 lbs, and the truck is usally loadded up pretty good( 3 bikes, 2 scooters, table, 2 20 lb propane bottles, 2 creats of wooden levelers, cooler with 2 cases of drinks in it, etc. )I get 14 to 18 highway going like 80ish not towing. I have the 2000 chevy hd 2500 gasser.
