I finally got the WFCO 7535 power center installed. I put it in a metal box and then mounted a 120 volt plug on top. I pulled some wire for 12 volt lights but I won’t hook them up now, we need to get on the road. This unit provides 120 volt for A/C when plugged into shore power and when I get a battery it uses 3 charging modes to keep it topped up. The blue box actually looks a little better in the pictures, I bought it for 5 bucks at the Northwest Christian School Thrift store. It was a box with 24 pullout plastic drawers that is used for storing screws, nuts, bolts, etc.
