I have a 1966
26' Overlander and have been told the Water Heater is bad. I was so glad to see your posting. I wanted to go with a tankless but was told by a service person at the Camper store that he heard it didn't work well.
Would you be willing to tell how much you paid for the unit and how much time it took to do the project.
I know nothing and am brand new to owning an Airstream...or any camper for that matter. Any thoughts are helpful. Where are you located maybe I can hire you????
