I have been towing a 2010 JK Wrangler for two years, using the Aventa bars that you have and an Invisibrake, which I can't recommend. I'm looking for something new to tow my Honda CRV (when I'm not bound for Moab). Thanks for your summary. By the way, I discovered that I don't need to leave the key in the accessory position while towing my JK. My steering does not lock with the key out! Chrysler tells me some do and some don't, and that they think it has to do with the state to which the JK was delivered. But I've towed my JK 9,000 miles with the key out, which is nice since you don't have to remember to recover it when you stop for lunch! Check yours by removing the key and trying to turn the steering wheel all the way in both directions. This works best on gravel. If it never locks, you are good to go.
