My Alpine coach won't start
Ed, the leveler so run off the house batteries, not the chassis batteries. The symptoms you describe indicate you have no (or too low) voltage on the chassis side, while you are plugged in the chassis side does not charge. Did you turn off the chassis battery cutoff switch in the battery compartment? What is the voltage when read at the chassis battery, saying your batteries are fully charged does not answer the question, we need the actual voltage to the tenth of a volt on the starting (chassis) batteries.
Other than that I would look at the ignition switch.
