Review on Gray ADCO 52258 Designer Series SFS Aqua Shed 5Th Wheel RV Cover - Fits 40'1" To 43'6 by Duane Kerr

So far (about one and a half months) through lots of wind, rain and some snow, this cover has served us well. We have a "27" foot mid-profile fifth wheel, which is actually 28 feet nose to tail. We're glad we got the slightly larger cover. There seems to be enough air circulation and, while not billed as "waterproof", the cover is keeping most of the rain off the roof of the trailer, which was our main goal. Four weeks before getting the cover, our RV roof was damaged by heavy snow and after that rain. The cover would have prevented the rain soaked snow from holding water near the vents, which is where our leak occurred. Our repair will cost $5000, but at least the cover will help prevent further damage until it goes into the shop in two weeks.The cover is fairly heavy and can be difficult to install. Figure our which end is front and follow the directions, rolling out from one end to the other before unfolding over the sides. Two people really help with this, especially when throwing the webbing under the trailer to cinch it down. Since the web straps aren't weighted, I used a simple hand-clamp as a weight: worked great. I suspect that failures noted in the reviews come from exposure to too much UV (from the sun) and from not having it securely fastened down, which could lead to disintegration in the wind.In a couple months we'll have an RV carport erected, but until then, this works well.
