Since all your problems are related to the slide-out I would suspect a loose wire in the junction box that feeds that slide. Follow the wire held up by a spring under the slide to find the location of the junction box. (also check that wire for damage) Disconnect from shore power before opening junction box and inspecting wires. Also could be a loose wire on the breaker but since it is more than one circuit that's doubtful. JM2¢, Hank
