Just FYI
I have a 31bhpr and during a complete downpour here we had leaking in the main slide. I wasn't parked completely level, the driver side was a bit higher. But the issue wasn't necessarily just that as the bunkhouse slide did not leak at all. The issue was the seal on the top of the main slide. There are two rubber flaps that did not lay out correctly and were stuck in the position I would think they would be in when the slide was out. I took a long stick when the slide was in and repositioned the rubber flaps to their correct position and all was well after that.
Looks like slide toppers next season
