I'm purchasing an enclosed trailer this winter for next season. From what I've read I should get as big as I can tow. I get that but what I don't understand is why so many people like barn doors on the back of the trailer instead of a ramp door. I have a 7x14 enclosed trailer that I have used for the past 15 years in my lawn mowing business. It has a ramp door and I think that it would be better than barn doors for loading a motorcycle. I know I could have barn doors and use a ramp but I just don't see why I would. Can someone please tell me why barn doors are better. I'm willing to listen.
