Do you already have aux braking system installed on the towed?
IF not then the Ready Brute tow bar comes with Ready Brake, a surge braking system.. This system works well when new but has one problem in that the cable that operates the brakes is like a parking brake cable.. It can rust and size up like a parking brake cable does if you live in the wrong part of the country.
(The solution is regular testing)
OTher wise I can not recommend a brand. MOst all makes have much the same offering.. I can however ecommend a TYPE
I use the kind where it has extendable arms so I can hook up "Off center" of at an angle. and it "Stows" on the RV with only the base plate left on the car.
Mine is a blue ox.. But as I said several other companies are like it.
