Review on Premium Waterproof Travel Trailer RV Cover With Access Panels - Tear-Resistant And Windproof - Fits 9'-10' by Keegan Herbert

Not waterproof and was told if it was it would promote moisture in trailer. Not true, there are vents and it's open at bottom, so lots of circulation. I had to make adjustments: First, the cover needs to be reinforces along all bottom corners. Trailers have corners and edges that will wear through the very thin material. Second, the zippers are front and back and when rolled up the roll droops down lower than the door opening, so you have to hold it up every time you enter or exit the trailer. Third, the 'flaps' that cover over the upper vents do need to be attached down somehow. The slightest breeze throws them up over the top of the trailer and if it's raining, rain gets in through the vents. I had to sew Velcro on to hold them in place. Fourth, the straps under the trailer have a hard to pinch buckle and to synch up the cover, the buckle is now 3' under the trailer. One end of the buckle should have been on the edge of the cover. Fifth, I wanted waterPROOF and had to spend an afternoon and money buying a water repellant to make it so. It was almost impossible to find a cover for my 15' Prowler and I'm grateful that I got this, but it was a LOT OF WORK to make it work for me.
