Looks similar to the AutoWeave cover except you’re using self stick magnets instead of self stick snaps on the trailer - right? How thick is the cover, the AutoWeave includes something like a 1/4” piece of hard foam. I’m guessing the only advantage is the magnet version is more forgiving when it comes to putting it on in weather extremes. With my Autoweave I initially installed it in 70 degree weather, if I take it off and store it in my truck bed and it gets cold its hard to put on because the material contracts, so I warm it up in the trailer first so it will stretch as needed. With magnets you shouldn’t have to worry about an exact fit.
