I pulled two different Wranglers. Tow bar is a Roadmaster Falcon 2, lots of miles, never had a problem. |Brake system RVI (
https://rvibrake.com/collections/sho...braking-system) same thing, used for a number of years, no problems.
I have to add friends have many different tow bars, some have auxiliary brakes some don't ( they are taking a chance in my opinion). All seem to work fine although each believe they have the best one.
Good Luck
