I always stored my trailer inside except for one year a few years ago. We purchased a
Camco cover that fit very well and we had no rubbing or other damage when it was uncovered after a long, cold winter with a lot of snow and ice.
It has substantial straps that go underneath the rig and also draw strings on the bottom, top and front/rear sections to tighten everything up. We were quite happy with it.
That said, we now leave our rig outside year round, without a cover, and have so far had no adverse effects. It now sits in the northern Michigan woods as you see here all year long. We will see how it is next spring.
I should mention that I have put on a very substantial liquid rubber roof coating over the past couple of years. That is the main reason we are leaving it without the cover this year.
