We have a 2021 Reflection 295 rl with 2 slide toppers installed at the dealer. The one on the back side is tighter than the front one. We were in a good bit of rain last week and what made me notice was when retracting the slide room the front one had a bunch of water pouring off and the rear one didn't. So my question is how do you tighten it up or should I contact my dealer to get it tightened or what? Thanks in advance for any help.
