I would suggest that the 15 AMP circuit in your home is not adequate to run your RV.
I would trip all CB in your AC panel, and then try plugging in.
Then turn on the RV master and only the DC converter. This will pwr the charger to your battery. On most RV, the battery will charge even though you have the DC master switch in the off position.
If you run the Refrig, this will overload house circuit.
