I’m not Seth, I don’t have the fifth wheel model, mine is the Fuzion 301, I’m pretty sure the garage is exactly the same in size. I had to remove a bed as well and it still rubs the bottom of the bed a little with stock wheels/tires. Not knowing how much extra height you have it’s going to be very tight. FWIW, being stock I have to be perfectly straight for the back door to close and it often rocks back & forth during transport enough to have caused some rubbing damage on the front wall but nothing that will take a lot of effort to repair for resale or when it bothers me too much. You’re going to be very tight on height. I think you should be ok on width but again it’s tight. With the wheels you have you’ll very likely have to take the roof off for transport, it would be way easier to go with a fiber roof in my opinion. Also if you have the table that pops up through the bed (we use it a lot) you have to be careful to make sure the legs are secure to the bottom of the table before driving in. Measure, measure, measure.
Congratulations, enjoy.
