All electric wouldn't be good if
1) you wanted take a long road trip
2) you ever wanted to sell the trailer
3) you ever wanted to boondock.
You could get around some issues by bringing a portable propane stove, and a cooler. Or not go totally electric but mostly electric. That being said, a trailer with an electric refridgerator is usually perceived to be
undesirable.
When we have camping parties, the ettiquette is to only use
12 volt utilities, as one electric heater uses up what four campers use. No AC,
microwaves, electric heaters.
