We've towed both the Grand Cherokee and the Wrangler (although only one at a time
) all over. Jeeps are perfect for towing. Just keep the transmission in park, unlock the steering wheel one click, and slide the transfer case into neutral. You can get a dummy key, without the digital security feature, that will let you unlock the wheel while not allowing the vehicle to start.
We had a friend who forgot to unlock the wheel once and towed his GC a couple of hundred miles with no damage to the Jeep. They are tough and will let you go anywhere you want to go.
