My only experience towing a car behind a motorhome was 4-wheels-down. Over the years, it seemed like there were fewer and fewer cars that could be towed 4-down, usually due to keeping the automatic transmission lubricated when the engine was not running. Automatic park brake is a new wrinkle. Steveo may be right that a fuse could be pulled for towing, but who knows what else may be on the same circuit. Perhaps something essential?
