I put this on my TC23SB. I needed to get the filter off the ground, organize the hoses, and have a place to store it. I had a small space under the sofa with an outside entrance. I used a regular full house filter with garden hose attachments on each end. Then a 10 foot hose from the filter to the trailer connections. A 25 foot hose from the faucet to the filter.
I made the holder from a 4 inch drain pipe. I looks a lot better painted, now all black to match the bumper. Cut it off at the connector end to get the expansion. Mounted with 6 inch galvanized carriage bolts.
Does a really good job and I don’t have to carry something extra inside for it.
