Towing a Jeep, Tow Bar, Braking, etc questions

I used a box brake for many years. Installing/removing does becomes tiresome if you stop a lot vs stay longer. Just stepping on the brake with the engine off bleeds the vacuum so that is a non issue for us.

Since you've got the box brake go ahead and use it for say a year then decide.

Last fall Roadmaster had a very good deal on the Invsibrake installation about $1100 and they gave me $100 for my old box brake. This likely didn't include the power cable and lights which was already on the car.
