Thank you for the comments. My water tank, pump, and heating duct are under the couch. I am still looking at the ladder to the bunk and mounting large hand holds to control my entrance and exit of the bunk area. Our dinette is free and clear nothing under it, and to tight to sit at. So I may remove it anyway. Carpets go under the dinette so it should be a clean easy thing to do.
To answer a question, I had my knee replaced, which gave me a blood clot in the right lung, which caused me to break by back. The knee turned out to be infected from the fist operation. Damn near killed me. After ten weeks in a full cast with no knee, I got a new knee, so special its in a study. My left ankle wore out because of the cast on the right leg. It took three years to come back somewhat, and my back is garbage, a brace on my ankle. Getting old is not for sissies, but every time I see our wounded vets, my troubles are nothing.
