Our Jayco stays in Az so we don't coved it. We have a smaller Sunny Brook trailer in N. Idaho and we were covering it. It has a luggage rack on the upper rear roof area and the cover was trapping a lot of water and I didn't like all that weight sitting on the roof for months so starting this year it is uncovered.

I was born with nothing and I still have most of it left.
