Good morning:

Check out the Jordan Research Corporation Ultima 2020. This controller is an electronic unit that is a proportional controller. It works by having a sensing cable attached to the brake pedal, so it
applies braking appropriate to the situation just like the old hydraulic tap units.

Unlike the majority of controllers, this one does not apply pulses or full on power when activated, only what is needed. I love it. No locked up wheels !

I believe camping world has them in the catalog. Jordan Research has a website, but for some reason I cant get to the 2020 page. Will let you know.
