New information to chew on. I jacked both front tires off the ground and turned the wheel all the way right and left with the key out. There is no steering wheel lock! Even though the owners manual says there is. So if I do not need to turn the key to unlock the non existing steering wheel lock, the whole disconnect the battery thing may not be needed. This would be in line with the way I tow the Jeep Commander. The only thing I need to determine is if miles are accumulated with the battery connected and the key in the off position.
