I have a 2009 GMC 2500hd diesel. The door sticker indicates a GAWR RR at 6064lbs and GAWR frt at 4860lbs. I am interested in buying an artic fox 811 truck camper with a dry weight of approximately 28...
With mods it will work, if you are ok with being over the GVWR. I haul a 3800lb commercial cap on my 2013 2500 HD with supporting mods. I went with 19.5s for 9000lb tire capacity on the rear, upgraded Bilstein 5200 shocks, extra springs to carry the weigh and air bags for leveling only. I drive over 20,000 miles a year, the truck drives great and nothing has exploded and I have not been arrested for being over the yellow sticker.
