Scott, it's hard to believe some of the things that happen in the manufacturing process. My A213HW was delivered to me with a regular water hose draped across the underside to provide toilet flush
, -no zip ties to the frame or anything. After a lot of trouble with leakage, the dealer replaced it with PEX on warranty. Haven't tried it yet, keeping fingers crossed.
We had a Palomino Gazelle some time back that blew pieces of styrofoam insulation all over the place when we turned on the AC. I talked to a guy in a 5th wheel camped across from me in Florida. He said he has the same problem and it's been going on for two years.
