The 110 was measured from the hot to the common (two verticals, and also hot to the ground). Actually I a measuring on the wires entering the switch panel, or breaker box.
Talking with Progressive briefly on Saturday they said they have found units with problems at the main power cord plug in on the coach. If that was the case why would I get 110 in the kitchen and the air conditioning and everything else working fine.
I'll take a fresh look at it next weekend.
