Trailer won't operate on plugged in power

Having a confounding problem. My Cougar RLS27 won't run on shore power, only on the batteries.

On my latest three day camping trip, when we plugged into the 30 amp outlet at the state park our trailer was read - no appliances, no 110 outlets. It would only run off of battery power. Before we left, we had the trailer plugged into a 110 circuit at home with no issues. We thought it might be the power converter, so when we got back I replaced it but no change. Interesting this is that it appears to have power at the breaker box. When I test from ground to all the breakers, I'm getting a 110 reading. Even getting power input to the converter.

Has anyone seen an issue like this and have a suggestion? Would really appreciate the help.

Thanks

    120V AC power comes from shore power source.......pedestal etc.
    Goes thru your 30A rv power cord to Main AC Power Panel thru the 30A MAIN Circuit Breakers.
    AC Power Panel buss is hot when Main 30A CB is Closed.....then the individual circuit breakers feed the various AC equipment when they are closed.


    SO if you have 120V AC power at pedestal and thru cord to AC Panel and CBs are closed then AC appliances and outlets should be hot


    Unless you have a generator... which gets plugged into outlet where rv cord is OR a transfer switch that is stuck on 'GEN'

    Sounds like it was a problem with the park breaker. Did you check for power at the park pedestal?

    Are you saying it does not work at home now after the trip to the campground?
