I got mine from either Rex Marine or Eddie Marine, think it was Eddie. Has lasted three plus years in the Florida sun and rains and has held up very well. It is virtually waterproof, at the time I think it cost me about three hundred bucks or so. Once you get the hang of putting it on and off, and mark the front with a marker, it only takes about eight minutes to have it secure. Light grey in color. I'm very happy with it. It does not cover the silent thunder swim platform. Think it's listed as a 30ft. cover, but fits very well and I just bungy cord it to the trailer. Nice tight fit, repels water excellent.
