I have had the Revolver X4 on my Raptor since last summer, and so far, it appears to be holding up well with no damage or signs of wear to the vinyl, but my truck does stay garaged when I'm not driving it. I like the way it i sits flush with the top of the bed, and I like that I can roll it up and open the whole bed without blocking my back window. If you spray water at the top and sides of the tailgate, you will get a little water in the bed, most of which could probably be prevented with the strategic installation of some weatherstripping, but honestly, it just hasn't leaked enough for me to worry about it. I have had a Roll 'n Lock retractable cover and a tri-fold in the past, and in my opinion, all styles of covers have their drawbacks and will allow a little water in if sprayed directly with a hose, but for me, the X4 works pretty well. I will admit by how low profile the WeatherTech Alloycover looks in pictures, but I haven't seen on in person.
