The tip we got about the on-demand water heater is to set the temp (104* for us) and don't mix any cold. It's mostly good...enough. Try it. The bigger issue is the waste of fresh water waiting for it to get to temp. A recirculating diverter requires opening the wall to add a line back to the fresh tank but would be great for boondocking.
I'm wearing trifocals now but my hindsight is 20/20.
