Thanks to everyone for the feedback! I'll hit a few of the websites and let you know what I end up doing.
Maybe i should open up an "RV Power Step Repair and Installation" practice with all of the experience I am getting on this one!
$125 to tell someone that I can't fix their step sounds like a good way to make money, and quick.
