Going out of state hunting in or around Utah? If you don't want to stay in a hotel, you can rent a trailer in Utah from these guys.

We rented a 23ft popout for antelope hunting in SW Wyoming. It worked out great! Much nicer than tent camping or driving to and from town every day.
It was much better than renting locally here in California, then having to haul a trailer halfway across the country.
We also got a generator, which we needed. My only words of advise would be to bring extra water drums and gas cans or you'll run out pretty quickly...
