Kinda like asking how to transport a huge load of cargo by air....you can either get a bigger airplane or carry less cargo. Since chopping up the Alaskan or leaving all your camping gear at home isn't possible, you probably need to go with the bigger truck. In this case, a 3/4 ton truck will be needed to SAFELY carry that Alaskan camper in my estimation.
Nobody ever complained that their truck could carry MORE weight than what they rolled out one morning fully loaded with passengers, food, supplies, camping gear, etc. However, a pretty fair amount of the WTW traffic relates to how to carry MORE weight (camper and all that stuff) when the truck suspension is sagging and a trip over the scales tells you that you have seriously overloaded the rear axle.
Post what the VIN tag weight maximums for front, rear, both axles and that will tell what you are up against.
