Broken Shower! Happened to You????

We owned a KZ Spree Escape and on our first long trip from NY to FL the shower drain cracked and allowed water to flow into the underbelly of the trailer. We actually didn't notice it right way but after a few days water began dripping from the underbelly and that's when I noticed the bulge. I put a hole in the underbelly material and water began pouring out. The shower drain P tube had to be replaced, a supported added and all of the insulation was replaced after the area was allowed to dry. We had the trailer for five years after that and no repeat of the problem which was fixed under warranty.
