Not a new camper but just picked up my new 2013 GMC Sierra Extended Cab 2500HD 4x4 with the 6.0 V8 .
Previous truck was a 2012 Toyota Tundra Double cab TRD 4x4 with the 5.7v8. The problem with the Tundra was very little payload capacity. With the gas tank filled my payload capacity was 1280 lbs. Just not enough payload for me.... Can't wait to start pulling my rv with my new truck! 4 months till spring and hopefully snow is gone!
