Thanks for the response Linda. I think I have it figured out from looking at a few other posts and pictures here on the site. The sofa is a jackknife style sofa/bed. I don't think it will be that hard to remove, which will give me access to the fresh water tank, water lines and pump, plus allow me to remove the wet carpet and dry it out. This site is fantastic!!
BTW, I just recently pulled and repaired the black and the grey holding tanks (1990 Winnebago warrior). Grommets had to be replaced on both. I didn't take any pictures as I was not aware of this site yet. But if anyone out there has questions, I can probably help.
