Carrying a camper and towing your trailer is 4.10 gear territory.
By the time you re-gear your truck and buy a Superhitch and a shortbed type camper with a slide-out, you'll be a lot of $$ into it.
You really have the wrong truck, I'd sooner sell/trade into a long bed with lower gears.
Then you have a large selection of older affordable campers (a shortbed with slide is going to be pretty new and very expensive) and if you stay with the same 8 or 9 foot length you were already considering, you wouldn't need the Superhitch. It would handle it all better too.
I know, you run what you've got... another possibility is a redneck toy hauler, that's a big enough trailer to put a camper on the front and your Jeep on the back.
But you still have those tall gears.
Between camper and trailer, he will be hauling 10K lbs and probably be around 18k lbs GCW. The stock gearing on his diesel will be fine.
