Have you bought a tow bar yet? I bought the same tow loops as you and just ordered a Ready Brute Elite II tow bar with built in surge brake. The system looks super simple and is a pretty genius design. If you go to
https://www.readybrake.com they are giving 15% off entire orders for the holidays.
I had my Maximus-3 tow loops sent directly to them so they could figure out which adapters would work. They confirmed their Barricade bumper adapters (part #10036) will work.
I haven't seen any of my stuff yet as I just ordered it on Thursday. I should have it this Wednesday and will report back then.
