You may have toggled the battery disconnect switch - often located by Fleetwood next to drivers left knee. Also - you likely have two solenoids in the engine compartment - one is a battery isolator (you should hear click when the engine key turned) and one an
Intellitec battery disconnect. Another possibility - you likely have an auto reset circuit breaker near the battery bank - when that goes toes up it essentially disconnects the batteries from the rig - use Google for pic as it doesn't look like std circuit breaker.
