I have been looking for a camper for my F350 for a while now, and I can't see that Arctic Fox makes any camper that will work with a typical SRW pickup truck. Even their lightest weight camper, the 865, that has no slide out, has a wet weight of 4200 lbs. My F350 with 11,500 lb GVWR has a payload capacity of 3960 lbs.
Part of the problem is the Arctic Fox Value Package that every camper they sell is required to have weighing an extra 600 lbs. Add that to their claimed dry weight, plus the weight of water, LP gas, batteries, and nominal camping supplies, and you are over the payload capacity of almost every SRW pickup. A regular cab XL trim F350 short bed truck may be close though.
I used Truck Camper Magazine's article to come up with wet weights of the campers. https://www.truckcampermagazine.com/buyers-guide/hard-side/arctic-fox-camper/
