Michael, the tow truck driver will have to remove the drive line if you plan to tow with drive wheel down
or will have to put your motorhome on a platform lowboy trailer. Damage will happen to your Allison
transmission if driveline is not removed. The tow truck drivers are experienced in removing the driveline. Last note: look into your Allison transmission book and that subject is spelled very clear.
