Another modification that we made was to install a Boler
holding tank under the Trill to save space inside. Originally there was a metal tank located in the back bunk.
My husband made a protective aluminum case and designed strapping to install it under the trailer. The case was lined with strips of Styrofoam to help protect the tank. Measurements were taken on the inside of the back bunk and under the trailer to position the water intake valve.
To empty the tank, we simply reach under and open the valve.
