I tow an 09 Wrangler Unlimited Rubicon and use the US Gear Unified tow brake, Blue Ox base plate, Cooltech wiring harness and Blue Ox Adventa tow bar. Your HR is pre-wired for the US Gear Tow Brake and the cord has an extra wire that charges the toad battery while towing. All you do to go is plug in the cord and break away stem and your done. I installed all myself and enjoyed it, and if you can use tools you can also. There are also other braking systems that I read alot of members are happy with besides US Gear, they are SMI and M&G. Also, check if your new Jeep has steering lock, (my 09 dosen't have steering lock), if it dosen't, you can tow without the key in the ignition which is really great, (no forgetting to put the key in when you drive off ).
Good luck soon to be fellow Jeeper
P.S. I love my new Rubicon it is actually quieter than my Honda was.
