we bought our Roo without a slide cover. we decided we would see if we needed one.
after 1 year, we had to admit our mistake. we should have had one installed before we bought our trailer. after countless
sweepings and seals with sap that made the slide stick to the side of the trailer, we got one installed at CW. it probably cost us more by adding it later.
but now we are so glad we did. we haven't had to worry about snow, but we have avoided leaves, pine needles, pine cones and other forms of debris. and once the seals were cleaned, no more sticking of the slide going out.
