Since we parked yesterday, the step would open and close each time I would open and close the door. I know there is a switch on the entrance console, but it did not matter which position the switch was in. 

Well that was just plain weird. 

I just noticed that the DD Prodriver was still on. Hmmmmmm. If the step thought the ignition was still on it would act like it was acting. I put the key in and out several times, switched to on and off several times but the Prodriver was still on. Hmmmmmm, some more. Just for grins I turned the wheel until the lock caught it. Voila, Prodriver turns off, step behaves normally. 

So, something about the way this coach is wired, the steering wheel lock has to pop before it thinks you are really off. 

Go figure.
