The real variable will be the actual weight of the camper. Spec weight and real world weight is often drastically different. Batteries add weight, propane tanks add weight. Experience would lay odds that you could easily end up a couple hundred pounds over weight. But that may or may not be the end of the world as there are a lot of folks here with tens of thousands of miles on their rig and all been slightly over published weight limits. With a couple suspension modifications, you might be fine.
