Top 3-4 Travel Trailer Bunkhouses

I recently purchased a lacrosse 318bhs at Tom raper rv. We really liked it until it started raining on our second camping trip. The carpet beside the slide out gets soaked. It has been back to the dealer twice now and going back for a third time this week. They cannot fix or even find the leak. It has been wet so many times I'm starting to worry about mold. Prime Time manufacturing does not seem to concerned about this issue and Tom Raper's service sucks. I would not recomend either one of them.
