Not sure if this helps you, but I have too been looking at trailer options for my Bikes. Go to wwwKlingertrailers.com, they have a very nice ramp free trailer, Other one I was looking at
was Baxley ramp free trailer, I believe both of them might have an enclosed options as well. The Klinger is made in Lower Michigan, the Baxley is made in Georgia but you might have
a dealer up in the woods where you are. Hope this helps you.
