My Fifth Wheel (2009 Cameo Carriage 36FWS) loaded weighs in at 16,000lbs with a pin weight of 3,500lbs. All weights are within limits and the truck sits level when loaded. I noticed that my truck sits about 4 inches higher in the back than in the front when empty. Does anyone know if dodge did this intentionally? If so why are the 4X4’s level when empty?
