Your JK is a lot different than our 2003 TJ, but sounds like the ignition lock is the same; all I do is turn the ignition key to the first "off" position (as stated in the owner's manual) before towing. I have a single ignition key so there is no bouncing or jiggling of a large set of keys that might dislodge the key from the correct position. We have SMI's StayNPlay system which is real good, no piston sitting on the floorboard that has to be moved before starting the Jeep after unhooking from the RV. A small piston is located behind the dash on the firewall and the control box is located under the hood, nothing is in the way of driving the Jeep like some other systems.
