This was a dangerous situation which I never thought about before your post. I worried about losing my brakes on a downhill and what I would do. I have turned the key off on my tow car and it was hard to steer and the brakes at first worked but after several pumps they became very hard to stop. I can't imagine trying to steer a MH with the eng off down a windy road. I wonder if the power steering pump would work somewhat if the eng was still in gear rather than neutral? Glad you OK.
The older vehicles, like in the 50's and some 60's, the automatic transmissions had two pumps. With those vehicles, you could actually push start the vehicle because the rear pump would turn the engine over if the wheels were turning.
With the new automatics, no engine power means no transmission action to turn the engine over. You will have no power steering and no engine braking with the engine turned off.
