However that might put the camper center of gravity further back over the rear axle, farther back than designed. With a dually, it will not matter, however with 16" rims and 3,042 pound rated tires (235/85R16E is standard with that truck) you might overload them. Moving the load forward even 12" will put much more of the weight on the front axle, and not also be taking weight off the front axle by having more hanging off the back of the truck.
The camper COG will be in the same spot relative to the rear axle on the long bed truck. The extra bed length is in front of the axle. Adding cargo in the "gap" in front of the camper will effectively move the cargo (camper + stuff) COG more forward than with the short bed.
