Looking for camper weight advice!
Sorry I didn't know how to title this thread specifically enough, and it's a long form questions, but here we go. Before I get started here is a list of useful info regarding the rig we plan to out...

The AF811 will be about 4000 lbs when loaded and filled and the 990 will be about 4500 lbs.
The AF811 long bed version will have almost no overhang and allow you tow without a receiver extension or maybe one that is 18" or less if your trailer has a short tongue. The 990 will minimally need a 28" extension to clear the rear due the rear wings that contain storage and the generator compartment. Your trailer sounds like a 3500 lb model which will put an additional 350-500 lbs of tongue weight on the rear axle.
The rear axle in your truck is made by AAM and has a 10,000 lb rating, but GM derates this axle due to their suspension choice - Your rear wheels have more than enough capacity and are fine under heavier loads.
You will most likely find that the springs are too soft and will need some help. You can preload the springs faster by using using blocks or wedges to keep the same spring rate but get less sag or you can add additional suspension components to to carry a heavy load. In either case I would suggest a stabilizer bar on the rear axle to reduce sway and check your current shocks for dampening ability.
My wag on GVW will be 12,500-13,000 lbs with about 8000-8500 lbs on the rear axle once you are fully loaded up and hitched.
