We got home from yet another wonderful trip safe and sound, but this time once I parked, the light switches in the entire MH would just light up white, but do nothing else, also the waterpump (same switches) and anything on the swtches would not work at all.   The Living room lights come on for a minute then timed go off.   Also the stairs go in and out fine, but the stairwell lock switch doesn't work either.   Any ideas?  The living room slide works fine.
