Our old dually has always run high in the back by a couple inches and often with a smaller load you could hear the overloads when they engaged. With the camper on and loaded it sits level. This is with none of the add-ons I keep reading about. We get no sway nor any of the other squirrelly handling on corners that I read about. If course our camper isn't a beast but loaded is a little under or right at the max load specs for the truck. How did we get so lucky to not be faced with all the hassles and expenses so many are dealing with. Just lucky we couldn't afford more camper maybe, or just the Guy up there really watching out for a couple of old farts.
