Four Winds Hurricane city water connection

Just a suggestion, but while you're at it check something else. We had a 2006 Hurricane we just traded in due to problems similar to what you're talking about. If I had noticed the issues earlier (which I think you have), I might could have avoided some of the later pain. Thor apparently never heard of water seeping in around screws. I noticed a little bit of rust around multiple mounting screws but didn't worry about it. Then the electrical outlet pulled loose and I replaced it, but couldn't get the screws to catch because the wood backing was softened by water seepage. Not problem - I could access behind it, so I just through bolted it with some washers; problem solved. Then the passenger side rear view mirror started shaking and I couldn't get the screws to tighten up. I decided the holes were stripped and decided to drill them out larger and put in a threaded insert to reanchor the mirror. Guess what? Water seeping around those screws had also rotted out the plywood backing at the mirrors! I spoke with the factory and the only solution was going to be to drill through the side of the RV, put a steel backing plate inside and through bolt the mirror on. Not fun. Went to trade it in last month and found out the damage was even more extensive than I realized - much more extensive. It had apparently been going on since I purchased the MH used back in 2009 from a dealer who led us to believe the slight bumpiness on the interior wall was due to someone leaving a window open during rain. Took a $6,000 hit due to the water damage but in light of the conditions they pointed out to me I felt that was more than reasonable. Don't get hurt by the same thing - caulk around all those penetrations and put some caulk behind the screws, too.
