I towed our 4dr Wrangler 4 down with no problems. I used a Blue Ox baseplate, motorhome mounted 10,000 lb towbar and a brake buddy braking system which I bought super cheap. CooltechLLC makes a great electrical tow harness which is super easy to use. I had a spare ignition key made without the chip, used it to unlock the steering column when driving. Blue Ox also makes a keyed alike set of hitch pins which are a nice option.
That's pretty much it, wiring harness went on in about 30 min. Baseplate was a challenge but looked and worked great once it was on. With the Blue Ox towbar one person can hook up everything in just a few minutes. When not being used the towbar stays on the MH and has a cover, don't have to mess with storage.
Hope that helps.
