Flat towing a Jeep YJ

What are some of the good supplemental braking systems out there?

IMO, there is only ONE "good" system:
Either the Ready Brute integrated towbar/braking system, or the companion Ready Brake system that can be used with any towbar.
Simple, mechanical, no electronics to fail, nothing to install and remove every time you need it.
It simply works, and works well, and it won't run the battery down.
And, it is relatively inexpensive, when compared to the magic electronic boxes.
It may be worthy of note that NONE of the presently available towed vehicle brake actuating systems have ever, to the best of my knowledge, been tested and approved by an independent testing laboratory.
