I finally had time to dig into this problem. I took all of your advice into account along the way. I ended up finding that the blue/white trailer brake wires inside the junction box on the RV were cut and arcing against each other. See the attached picture. If you look closely, you can see the black arcing on the blue wire. The brakes work great again. Thanks for all of your help.
