So, we had the same issue but with a 2018 Raptor 353TS trailer, so I'm not sure this information applies. John's suggestion is great and would have been my first choice. However, we did not have the opportunity to do a "test" load with a dealer more than 100 miles distant.
So I took some
VERY CAREFUL measurements and then did a scale drawing. I was very confident that I could get my Can Am in the trailer based on my measurements. The biggest issue for us was width; we have 67" of width and a 64" vehicle. That's not much extra, but it works. Forget about getting in the bathroom or walking through when the SxS is loaded.
Also check your length. We needed the 13' garage to have at least a foot of space for tie downs, etc. In the back, we lost almost a foot of garage to the 3-season sliding doors and the party deck railing. In the front, you really need a sliding glass door rather than a "swing into the garage" entry door. With the swing in door, it is blocked when the SxS is loaded (or consumes about 30" of your garage length) and makes tie-down almost impossible. So if you have an 11' garage, it's likely to not accommodate a 10' SxS plus everything else. Loading can be an issue. The 3-season patio doors and party deck railing reduce the opening width as well, so make sure and account for that.
Then there's getting the driver out! We cant' back the SxS in because we need the steering to avoid the bathroom wall/door. By driving straight in, there is not room to get tubby me out the driver's side. So it means crawling across the passenger seat to exit on the passenger side. I also put up some tire height sheet metal along the wall on the driver's side. This allows me to "lightly scrub" the wall without destroying the finish. Not much pressure, however, to avoid blowing out the wall.
All in all, with careful measurements and a good amount of thought, what you are proposing MIGHT be doable. We love our rig and combination. I love the 2nd bathroom, party deck, sliding doors, etc. But you want to be awfully careful with your measurements and confident that it will work - lots invested in your precision on this issue.
Good luck. Some pictures of our process and the end result:
