i received the following from the OP this morning. he requested that i post this for him:
I think I figured it out I found this at another part of the RV I think it was an old-time wire connector instead of using wire nuts they use it to join two wires together. the other part was what I thought was a plug-in was simply an empty area where the other wires used to go into to connect to another wire.
If this makes sense to you could you post this picture with this thought and thank everybody for their help and that if anybody else sees a plug like this in the future we'll all know what it is.
Thank you once again for all your help. And with most old RVs the work is never done I'll keep plugging along no pun intended
Have a great weekend ended and a upcoming week.

Just my humble opinion. :-) get someone who is knowledgeable with electricity. And they can see the Moho and answer your questions and do the work. If you have no experience it easily could go very bad.
Looks like the back part of a duplex outlet with contacts for ground and pins to plug in Hot & Neutral from the missing half.
Probably a manufacturers attempt years ago to come up with an easily installed (for the manufacturer) device for RV's that would be slimmer then a standard duplex. I know mine are kind of that way (without the plug in part)...which makes it difficult on the road to just put in a duplex outlet from Home Depot.
