Did your dealer know how to access the valves for the hot water tank? Mine didn't or at least the guy who did the walk through didn't. He told me I had to access it through the rear storage compartment and remove a barrier to get to it. So what did I do...I listened to him when I de-winterized the trailer and complained at the Jayco designers the whole time until I noticed a little hatch cut in the support for the lower bunk. My complaining then shifted to the dealer.
