We took the plug apart and cleaned the contacts. That didn't help.
I'm not sure how to check if there is power leaving the controller. It lights up when you press the slide thingie

.
I have power to the 2nd plug which is up on the side of the bed. Gonna change the plug at the hitch to see if that works. I believe that's got to be the problem. You're right Craiggo, It's like chasing a Ghost. Thanks for the help, Sometimes just bouncing info off of someone else helps.
