I have a 2010 Autoquest 115 and on my first trip out last year i had a water leak from a push in plumbing fitting under the oven. I replaced the fitting and all was well until this year when i refilled the water system after the winter and then i had no less than 3 leaking fittings. When i drained down last Autumn i was very carefull and even blew water out of the pipes so i know it was not frost damage. I have now changed all the fittings for what seem better quality. I wonder if anyone else has experienced the same problem. Steve.
