It has been a long time since I have sparked such humor in a thread. Thank you all for adding common sense to my thought process. Sometimes when your trying to solve a simple issue, you get tunnel vision
Basically I have a 50 amp service in the back left of the RV with one of those Round connections. All I want to do is disconnect it, and run a new line so its in the storage bay. I will be installing a new round Marinco plug in the storage bay, and using my 50 to 30 amp adapter to use a much easy to handle 30 amp cord. We only have 1 AC so need for 50 amp will be rare.
The adapter I was thinking about would have allowed me to install a flat receptacle in the storage bay instead of the Marinco...
But I now see the light.. Thanks again for not making mamma bear a very rich woman as she cashes in the life insurance policies :-)
