April 24, 2010I have a 2007, 2500HD, four door with a short box. An automatic trans, 4x4, 5.9 Cummins, 4.11 gears, HD towing package, GVWR 9,000. I am looking at getting a 5th wheeler but am not sure what this truck will handle in the way of hitch weight and GVWR of the 5th wheeler. I do have Firestone air bags on my truck now because I have been carrying around an 8.5 foot 3,000lb GVWR truck camper. I would like to hear from experience so I don`t have to learn the hard way. Thanks for your help.
