Be sure to follow the rule before you head out.
Rule: You must post before you leave.
In the US, do you have male sockets at all? We have those on caravans/RVs for shore power in Australia, so you can just plug a regular extension lead in.
I’ve seen a pronged socket for sale, but never seen them applied since I’ve never been in an RV.
