I used to tow a 2004 Wrangler A/T, and we now own a 2006 Wrangler Unlimited with an A/T.
With the A/T, the transmission is actually put into park, and the transfer case into neutral. Tends to freak some people out that the transmission isn't in neutral, but it's no longer in play.
I had telescoping arms on a Falcon 2 towbar. I would drive the Jeep to the back of the MH, put it in park, connect the arms but don't extend them at this point. Set the parking brake on the Jeep, put the transfer case in neutral, and the transmission in park. Now slowly release the parking brake. On level ground, should be no movement. I would then walk in front of the Jeep, but not between the arms, and use my butt to push the Jeep backwards until both extendable arms "popped" into the lock position. I could hear the audible clicks, and see the latches seat. I was confident at this point the arms were locked, and the Jeep's transfer case was indeed in neutral.
The only tip I would add is to have a non-chipped spare key made. It will unlock the steering column for towing, but will NOT start the Jeep if someone hops in it at a rest stop!
Picks and details of my previous setup here:
http://2manytoyz.com/toad.htmlI retire in 5 years, and will trade in our TT in the next year or two, and buy another Class A... and modify the 2006 Jeep for towing. Really is a fantastic setup. Had to sell my previous setup to buy a house. House is almost paid off, time for another toy!
