imho you had better carefully measure the actual trailer width and the actual door width. And verify if you have a direct shot at backing into the storage bay. Best course is to unload and hand roll the trailer into the bay and easy if no steep slopes. If you plan on unloading with the car on it you had better have some good backup skills and do it with plenty of light. Cause it looks tight till you prove otherwise..... not to mention height....
For the car fitting the trailer ...... with that front wheel stop I would wonder about the fit. If it has the low front rail you get a few inches overhang BUT Even if it fit I would suspect the balance. If this is a new trailer purchase I would strongly suggest you go with a 12'. And since 12 is typically a little wider getting it in an 8'-6" door may not work. I believe 102" is DOT max trailer width depending on your state. I had a Gen 1 on a 6x10 and it worked well and I actually modified it for my Can Am with 90" wheelbase ok but not as comfortable towing as with my new 7712 Aluma. My $.02

Thanks for the helpful input. I remeasured storage door opening and it is 106”. Looking at single-axle Triton 12’ trailer with a 72.5” bed width. Our 2025 Rmax2 xtr indicates a machine width of 66.1”. Do you find any red flags with this? Opinions/insights are appreciated!
