I am glad that your tankless water heater works now and that Girard has perfected their equipment. For me, I just prefer the old fashion tank type solution. We camp most of the time in the great Missouri State Parks where water is not available at most sites, therefore, conservation is important. Endless hot water is not a luxury that we can use. I can see for a camper using full hookups, the tankless water heater would be great. I also use a filter and pressure regulator.
