The Cougar has had a lot of issues with plumbing right from the start. Out of warranty now for over 2 years I am sick of fixing it. I have gone as far as removing the shower and resetting it with new caulk. Camping World service in our area is horrible and weeks out for appointments so we gave up on them. I am just sick of taking it apart and putting it back together. We had a laundry list of problems when the Cougar was new. It took CW 14 months to get it straight and they never could stop the plumbing issues.
