I have had many problems with my B+. First night out the A/C quit if anything else was on (like microwave) and then quit entirely. Kept running in and out of coach resetting the breakers. Finally wires started crackling from the A/C so shut it off. Other problems include water leaking from the A/C unit and vents, breakers tripping, rough ride and drawers flying open all the time; grey water handle broke and not closing properly, water leaking under the sink, and finally no power at all. Batteries will not hold a charge even after a new battery is in place. Any ideas from anyone?
