Why would you need a 1 ton? At 10,400lb GVWR any 3/4ton could tow it, heck a properly equipped F150HD could as well. If it was a 5er you might need a 1 ton but as a bumper pull you only need ~2,000 payload and a big enough engine.
The Arctic Fox 30U is large and heavy. I would not want to pull it with a half ton truck regardless of the engine's power. A three quarter ton would be minimum for me. The tongue weight could be 1400 pounds not including the weight of the hitch. That is a lot of the half ton's payload devoted to just tongue weight. It is also probably more tongue weight than the stock receiver is designed for so an aftermarket receiver would be needed. Add a bunch of stuff in the back of the truck, people, dogs, bicycles, kayaks, etc. and the half ton is loaded beyond manufacturer's payload if not towing specifications. Full timers take a lot of stuff with them, after all they are full time living in the coach. For me it would just be too much for a half ton truck.
