Hi,
I added 2 additional shore power cords. One is 20 and the other is 15 amps. I am able to heat 100% electrically but I do need 45 amps during the worst of the winter.
In summer time I use one of the extra shore power cords to power the electric water heater.
Before I had a hybrid inverter/charger I'd use one to power the converter and then use double conversion to power the RV. That allowed me to use 23 amps instead of just 15 without tripping the shore power breaker. That was quite useful when I did not have access to the shore power breaker panel.
My favorite heaters are oil filled.
I have replaced nearly all the OEM outlets with much better ones.
