That's 5-700lbs more than I got sitting on a short bed 2500 and I'm comfortable hauling it. Full timing? I'd want a bigger truck, but I believe a newer Long bed dually is plenty of truck in most conditions. Not like you're going to get more gnarly off road with the same weight on a bigger truck. Still 12' tall over 8' wide and a high center of gravity.
As long as the truck is solid and in good shape it will handle it. Although if I could cut 1/4 to 1/2 a ton off the back with a different brand with acceptable feature I would if I was traveling a lot of miles and off road day in day out. I'm not sure TCs get heavier by the foot than AF and the other big double/triple slides. As full timers you'll, I think, inevitably also have more weight aboard with belongings than the avg weekend warrior. Aside from theft issues, a small enclosed trailer for everything but the essentials in the camper may be a good move. Will help with not having to be as weight conscious.
Sounds like fun though!
