Camper reno pt.4 electricity maybe

I was under the assunption that for shore power all I had to do was connect it to my house because it was 110v. After doing some reading I think I might require an adapter to make the electric work. It says it can help, but in order to do all of that should I put the money from my next paycheck into a battery. Like does it need a battery for shore power? I don’t know but I am trucking along. #camper #renovation #blackwoman
