Towing a Jeep is about as easy as it gets. Buy a 4WD Wrangler, automatic or manual transmission doesn't matter. It'll have a transfer case and that's all that matters. Then read the the two pages in the owner's manual about recreational towing.
You'll also need a tow bar, mounting brackets, and some sort of braking system.
I, like many others use a Readybrute tow bar because it has built-in braking so I don't need anything else like a brake buddy. I got my tow bar with blue ox ends and have a Curry tow bar mounting plate. The mounting plate took a couple of hours to install but costs a quarter of what the other vendors charge. I went to a trailer shop and bought a trailer wiring harness and wired in a second set of lights in my tail lamp housing. Took all of 30 minutes to do and cost next to nothing. A bonus of doing it that way is that you don't mess with any part of the Jeep's electrical system and all the power that is required is delivered from your RV. All told I have around $1,500 in the setup and I've pulled my Wrangler all over the place. Another good reason to pick the Readybrute (in my opinion) is that it is made in the states.
