I just posted a similar question for my Dodge Ram 3500. I am looking at smaller campers than originally because I just don't want to spend another 5k on truck mods, wheels and tires and fancy hitches. I may still upgrade tires. If I go off sticker GVWR I have 10,100lbs, If I use combined axle I have 11,700lbs. Tires are 2731, so looks like they are my current limiter.
My initial list that I have ruled out as too heavy: Cirrus 820, Northern lite 8.11 (used), Adventurer 89FS, Bigfoot 2500 (used)
New List: Cirrus 720, Northstar Liberty, Capri retreat, Bundutek Bunduvry
I have never camped at a campground with hookups, and never ran a generator. It's hard to find newer campers that will still allow us to do that.
