Hello there, I was trying to determine if there are any options out there for an electric water heater that is plugged in. The tank in the RV is only 6 gallons and I am quite sure the wife is going to give me hell for not being able to get the soap out of her hair. The issue is the RV runs on 30 amp and the more I read the more problems I find with this setup. I was hoping for a simple plug in the bathroom wall solution for heating the shower water. Any advice would be much appreciated!
