My Prowler 27P RBS is an awesome trailer. I love it. There is one problem that I can't figure out. While traveling in the rain, water gets into the trailer. The rug in the slide and in the trailer gets wet. This does not happen while parked in the rain, slide in. Nor while camping in the rain, slide out. My thought is that the rubber seals on the bottom of the slide are not doing their job. Water comes up from the road and gets in. Any suggestions or thoughts would be appreciated.
