I pull my 2010 Jeep Wrangler with my 31 foot Class C RV. Worked perfectly as advertised, the Ready Brake is impressive on how well it works.
Interstate, rolling hills, and some pretty crappy roads along the way and this system is awesome!! A pure and simple mechanical system that you set up and adjust once and you're done! Hookup takes minutes! Unhooking takes even less. And a hell of a lot cheaper than the box brakes by Roadmaster and the like!
