My guess is that's where you plug in the short MALE plug so you are now powered by the motorhomes GENERATOR.. Older MH's don't have the transfer switches that the new ones have.. ;)
So, when you need to run off the gen, plug the short male plug into the female box. When you want to run off the camp grounds power, plug the short male into a 30 amp extension with a female on one end and a male on the other..
Good luck!

This is probably your answer. Your generator powers that outlet, and you have to plug your RV into it to get generator power. My 2007 Winnebago does it that exact way. I actually prefer that to an ATS as there is less to fail.
