I have an '05 Silverado Duramax Diesel 6.6 the usual specs on towing, eg GVWR 9,200, GCWR 22,000, Hitch 12,000, 5th Wheel 16,000. I have read all of the posts and gone to the fifthwheelst.com website, but do not have the luxury of weighing the Heartland Bighorn 3055RL I am looking at online and negotiating a potential purchase. Does anyone have the same setup with TV and RV? If so how goes it?
