I have a 2014 Prowler model #18PRL. Discovered during our last trip that the tail section from the tub drain was not attached to the pee trap of the drain pipe.Most of the grey water was going into the drain pipe but some was not.Bought the trailer new this spring and have been out 8 times this season.I believe the drain was like this from the time we bought it.Grey water has finally saturated the fiberglass insulation in the sealed underbelly to the point that it has seeped through the protective plastic that seals the underbelly.That is how I discovered the problem.My local dealer has the trailer and will repair the drain but tell me not to worry about the insulation it will dry.The also tell me that this is Heartlands recommendation. I find it hard to believe that the insulation will dry,it is completely saturated.I also have a concern about mold forming or any other problems that might occur because of grey water draining into the sealed underbelly.My question is.Is this standard operating procedure and if so why?If not how do I go about getting the insulation replaced.My dealer tells me to make it known to Heartland so that if something happens down the road it will be documented.This seems completely insane to me.The trailer is under warranty and has water damage.The insulation needs replaced in my opinion.Advice and recommendations needed.
