Our HotCart3 has been flawless since we purchased it. I’m especially impressed with the efficiency of the tankless water heater, also how quiet it is when we utilize the hot water generator without the pressure washer. One suggestion; the piping coming down out of the water heater could use a bracket for support. My fear is that while moving the HotCart if the water supply hose were pulled on, it could potentially cause damage up into the tankless water heater itself.
