If your Jeeps are lifted, modified, big tires etc. I don't think you'll be able to transport 9-12 Jeeps in 1 rig. You'll most likely need at least 2 trucks.
We've used Nationwide United Auto Transport several times in the past for
vehicle transport and they always come through for us.
Give them a try
