Bill:
Glad you got the motor fixed. I would agree with other posters that replacing the controls with either a Gama or one of your own design would be a good thing to do. Controlling the jacks manually is fairly easy, you need Reversing controls as described on
this page at Gama. The ignition/brake interlock, automatic leveling and ground sensing functions of the Atwood system would be lost, but with the remote you can be outside leveling the coach and see what the levelers are doing.
I did find my motor on eBay, you may also have good luck doing an internet search for the part numbers on your controller.
