Valen, I don't know what you mean when you are asking about a 7 ft door. The trailer is 8 ft wide, and you cannot reasonably expect to maneuver it into anything less than 10 ft wide. My trailer carport is 12 ft wide, and I have to work to back it into that.
Now, if your garage opening is 7 ft high, It should just BARELY squeeze in. The "down" height of the roof is 6 ft, but that does not include the Air Conditioner and I don't know if the one on your trailer would add more than a foot to the roof height. As I recall, my trailer's Air Conditioner (which is OEM), adds about 9", so it would have fit except that I added spacers to the axles and mounted larger tires which raised everything about 3 more inches.
So, 7 ft high is a "maybe" in my opinion. It will be close. If you can measure the roof height and the AC height of any trailer you are considering, you will know for sure.
