Josh,
Looks like you've got a nice toy.
I have a similar setup. I ordered my truck with the camper package so it handles it quite well.
I weighed it first thing and found that the camper was just a little over 4000#. That put my RAW at 6660# with me and a small amount of odds and ends on board. With the AF990 it added less that 200# to the front axle. I haven't re-weighed it but estimated it to be 3900# completely empty.
The tires were rated at 6200# (460# less than actual) so I put on some 3750# tires.
The camper brings the rear end down about 6" and the right side is heavier so I added Airlift 5000's to help balance it left to right and bring the headlight down a bit.
To balance it left to right you'll need to plumb you're airbags separately.
You'll also need to add air to the airbags and then let the air out until the springs touch the overloads. Too much air will make it sway a lot worse that none at all.
Did 5000 mile trip last summer and the only issue was heavy cross winds. I debated Torklift stable loads or a sway bar. Ended up putting a sway bar on. That really stopped most of the sway. Went up into the Smokies this past weekend and it handled great.
