Towing your Mopar

If going a long distance (cross-country as you suggest) I think I would put the rear on the dolly and drag it along on the front wheels. It will be more stable with the center of gravity lower, less parasitic drag / wear on the rear, no bother with the driveline, not to mention the car would be immediately available to drive if necessary in an emergency or breakdown of the tow vehicle. Just make sure to get the steering centered and secured (not just the ignition lock) with another safety device or method of some type holding the steering wheel. A club tied off in both directions would work, just for added measure.
