then people can answer your question.

This rig was a trade. It's old. Got it for a project. Tons of things to deal with. The kids are using it as a playhouse. Just going to spend some time playing with it. I would have never bought one this way. Anyhoo...there is a female in the back of the rig in a storage cabinet under the rig. Next to the female is a junction box with no cover just exposed wires. So I wasn't sure which one actually was intended to go from the rig to the box.

I believe that the out let you are looking at is the outlet from the generator. to use it you plug your 30 amp shore power cord into that outlet and start the generator. You do have a 30 amp shore power cord with a 30 amp male plug on the end don't you??
You will not or should not ever use a cord with two male plugs, one on each end, they call that a sucide cord. So let us know what you have for a shore power cord. And yes the camp ground pedestal will have a 30 amp female receptical so your 30 amp shore power cord will plug right in to it.

A cord with two male ends is commonly referred to as a suicide cord. A major no-no. Something missing here. Your rig should either have an attached cord or have a male connector to connect to a standard power cord with one female end and one male end.
