Having suffered a roof failure on our previous trailer and re-roofed it by myself, I was tired of constantly checking the top of our 2015 201UDS for wear & tear. I did my research, opted for the RV version of rhino shield & chose RV FlexArmor. I visited a facility, met the franchise owners, watched them actually do the work, and decided that was what I wanted. It's guaranteed for life, transferrable and was less than I expected ($3000 total) which included new roof hardware, a new antenna, and the Maxx Air vents.
