Convert our Trailer's electrical system from 30 to 50 amp

Bring an extension cord and plug the beer fridge, party lights and other outdoor stuff into the extension and run the extension to the 20A outlet on the pedestal. that will take those loads off the main 30A panel.

My TT is wired with 6 15A circuits:

1. A/C
2. Microwave
3. HW heater
4. Converter
5. Kitchen/bath outlets
6. Bdrm/LR outlets

So you can see that 6x15=90 but main service is only 30A, so you can't draw the max on every circuit.
