HI! I am so interested in your postings. I am in the process of working on an '81 Excella 31ft and have a few problems of my own. Your new 12V system looks great. I've just found the boards for mine and will tackle this soon. Please keep us all updated on your progress. Best of luck and don't worry about that short term buyer's remorse...I know when I have unforeseen problems I tend to slip there for a moment too! I begin to think of her as a money pit! It's only temporary! Good Luck and keep up the good work.
