Hello, we just purchased a 2019 Thor Quantam with a tankless hot water heater and seem to be having the same inconsistent hot water issues as described above. The sink in the bathroom gets NO hat water at all and the hot water in the shower is very limited. We have an app't with our service team in a few days. Should I mention the adjustable pressure gauge right away or wait for their assessment? I also purchased the coach winterized and had some start issues with that as well.
