I cracked the tank in our Caravel several years ago. A local trailer repair shop would
not touch it because he did not want to deal with the sheet metal under the trailer. I
removed the toilet and then removed the tank through the closet on the street side. No
one had a tank so I took mine to Inland RV and Andy used it as a model to get a new one
manufactured. I believe he now sells them. It want back in through the closet and now
works fine.
