I am trying to determine if I can squeeze a 1980 in my garage. I measure straight from the back wall to the door and I'm right at 21 feet. If I angle I can get close to 22ft 6 inches. I see the length online stating with the tongue open and motor trimmed the overall length is 22'6". Has anyone measured with the motor all the way trimmed down, turned to one side, and the front angled down? Will it free up a few inches? Anyone have a suggestion on how I can determine the fit?
