I don't know what motor home you have. But, to release the auto park, chock your tires both ways so it doesn't roll either way. Now, scoot underneath the motor home right behind the left front wheel, scoot past the frame and look up. You will see a clevis with a pen. Have someone inside the motor home with their foot on the brake pedal. Have them turn the ignition on but not cranking and pull the shift lever out of the park position. This will release the tension on the clevis pen. Remove the carter pen and pull the pen out. If the engine is hot, you can burn your hand or arm on the exhaust pipe. Now you can drive but remember you have no park and no park or emergency brakes.
