I recommend it, read why !
I have a 1997 class A diesel pusher still running the original water heater, a suburban 6-gallon tank propane unit. I was going to install an electric point of use water heater inline before the propane water heater. The more I researched and considered I may not have the electrical requirement in all situations, the more I decided against it for now. I use the coach for work travel and usually have unlimited electrical, but it can be delayed for a week or two upon arrival. That being said I decided on this Fogatti because of the on-demand feature and I believe it uses far less propane than a tank heater. I have been using the Fogatti now, every day, for a month. Working perfectly and yes it will heat water as long as you want or until you run out of fuel for it. I may install an electric on-demand/point-of-use heater in the future just to save on propane (LP Gas) when parked for months on a job. The Fogatti was worth the investment, I would buy it again for any RV I own.
