    Summit RV in Ashland, KY hadn't seen one but they installed it for me and were impressed.

    Jayco 154bh tank upgrade

    This tank is the perfect upgrade for a Jayco 154bh. Roughly doubles the fresh water capacity. However, there are some limitations related to the organization of the utility cabinet on the trailer to be prepared for. I had to move the water pump approximately 2 inches and relocate some of the PEX water lines in order to fit the tank. I also had to remove a cabinet brace to get the tank in place and replace it after the tank was installed. However, none of these issues are related to the tank itself, they are due to poor planning of the layout of the utility cabinet itself.
