Oh yeh. Last trip out lights were going off and some on by themselves. The trouble lies in the size of wirenuts they used in my rig. Too many wires jammed into too small a wirenut. The vibration caused some or one? to fall out. I think I've just about redone every connection and then I find another. Remove the fixture and fish around in the ceiling for the connections. skin out the wires so they fit better in the conector and when you are done wrap some GOOD tape over the whole thing. RVIA what a JOKE. They are suppost to set standards. Cheaper the better is their motto I guess.
