We have a 2008 28ft North Trail. Absolutely love it except that when we went to take out out Memorial Day we have leaks all over. Under Kitchen sink, shower and bathroom sink. I should add that we did drain and put in RV winterizing antifreeze. From the looks of it all connections seem to be loose. Also we had a downpour and the slide out started to leak. Has anyone else had this problem with their North Trail Travel Trailers?
