I have a 2013 Cougar 27 RLSWE. While using my trailer in December, I noticed that the carpet was wet in the bedroom next to the wall going into the bathroom. The sink is directly on the other side of the wall so I checked all of the water and drain lines under the sink and could not find any leak. I took it back to the dealer and they discovered that the drain line that runs along the length of the wall before it drops down into the gray tank had cracks in it. Has anybody else had this problem. Even though my trailer is over a year old, the dealer covered the repairs under warranty. I have attached pictures to better clarify my description.
