When we first started RV shopping, we had tankless water heater as a desired item and thought we might upgrade to one. However, after using our standard electric / propane tank (12 gal) water heater for over a year full time… we've never run out of hot water. Even with visitors staying with us. So, the Truma tankless fell to the nice to have but not necessary category. I have enough projects on the to-do list… ?
Why don’t you have a tankless water heater?
