I dry camp most of the time and have a very limited supply of fresh water and grey water capacity.
That water supply limitation is what might be the defining issue.
For those who prefer that type of travel, then a tank water heater model is probably the right choice.
For our purposes, the holding tanks are too small (fresh 82, gray 102, black 65) to be nothing more than a convenience used while actually mobile. We are always on full hookups for overnights and destinations, so the premise of continuous, constant temperature hot water is where our demand (Truma) water heater works better for our mode of travel.
