DFK, Yes you have a legitimate concern. I did think about that when deciding the length of this tank, so I did not make it as large as my original ideas were. My installation was done with the bathroom out, so I haven't tested it 100%, but I think this tank can also be taken out without disassembling the closet. I was actually contacted by a fellow with a Globetrotter that was fitting this new tank in his. I'm not sure if the Globetrotter has a larger closet or not, but his idea was to cut a 5 or 6 inch tall section out of the wall at the bottom of the closet, under the gaucho. This hole would not show except in the closet. Then, he slid the tank under the gaucho, through the closet and under the bathroom fiberglass. It worked for him. I think the same method should work for the Caravel
if the tank will not fit otherwise. I hope to never need to know for myself, but I will say this method worked for him.
