I was getting frustrated trying to get a service appointment to have someone look at the leaky shower faucet in my HTT. I had replaced the shower hose and handle but it continued to leak. Purchased a new faucet assembly from the dealer and thought it looked like an easy swap out. I located the access panel to the plumbing in the rear bunk area and went about replacing the whole fixture. Pretty simple removal and replacement.
When I inspected the leaky faucet, there was a crack in the fixture where a very small pipe/tube connected the hot and cold water inlet. Probably saved a couple hundred dollars on the service call.....
