I've had a Truma od water heater in my 2018 rv for four years and have had zero problems with it and plenty of continuous very hot water. Certainly hot enough to be super uncomfortable and maybe cause an injury. Dunno about others but am I just lucky?
Truma is a higher line of On Demand(Germany) and has a better track record. Truma replacement would require running the control communication cable to a spot inside for the wall mount control. Truma's also require once a year decalcification, kind of a pain to do, just time consuming, not hard. Doug
