I originally decided not to purchase this cover due to some reviews that said the material tore very easily. I shopped around and visited the dealership that I purchased my trailer from, and they highly recommended this cover. I took the chance and purchased it from ebay. When I unpackaged the cover to install it I was pleased in the quality of the material. It came with six tire covers, a ladder cap, gutter tip covers(I used tennis balls instead), and extra straps. You do have to be careful installing such a large cover on a large trailer. You can't pull it from the back and expect it to slide up the front or you WILL tear it. I installed it with a little help from my seven year old daughter without any tears. It fits good on my Grand Design Reflection 315 RLTS. I will see how it holds up through our central Indiana winter. We are out in the open without much to block wind. So far it has been unfazed.
