just for the record, on Fleetwoods your hot water will not work if your outside faucets are in the open position with the shower valve in the closed position. Don't ask why, just accept as a simple truth.:h Outside faucets ? The only outside faucet we have is the shower (outside) faucet. Useless item as we have never used it in any rv we owned. Would be afraid too anyhow as they are made so cheaply.All they are good for is to leak..But then we dont own a Fleetwood.
