I posted this problem a month or so, now front and rear are both involved. My 2003 Beaver Patriot Thunder was on our property in TN this October when temps were getting into the 40s at night. I started using the heat pump in the front Dometic AC unit. After running for awhile it started leaking water into the coach. I went up to the roof and made sure there was no debris in the pans and that the drains are clear. Still leaks. I tightened the 4 screws that hold the AC unit down a couple of turns to make sure it wasn't leaking under that. Still leaks and am contemplating getting a new seal. Now home in Central Florida I again took the covers off both AC units to make sure they were clean with no debris. Last week my Wife's Sister came to visit. We put her up in the RV and I turned on the rear heat pump to keep her warm. You guessed it, it also started leaking in the middle of the night. I have heard of some Beaver coaches that have drain tubes. I know there is not one in the rear because a friend and I replaced that whole unit last June. I looked and can't find anything like that in the front either. The coach is parked on level concrete in both places with bags dumped. It does not leak with the AC running to keep it cool in the coach. Help!! What could be causing these leaks to come into the coach. Reaching out to several forums at this point because I am stumped!!
