Does anyone make a full boat cover/shelter that is tower mounted? I am envisioning something like those portable garages except instead of using flimsy poles that break apart in a slight breeze, use the rock solid structures that already exist (your tower and the guide rails on the back of the trailer) Seems like it wouldn't be too hard to fab up something that uses the tower as a center pole, the rear boat guides on the trailer as support in the rear and then some sort of removable pole that can be mounted on the front of the trailer. I would still use the regular cover as well.
Anyways, anybody seen anything like this? Pics would be great.
