I've used the US Gear Unified tow brake in 2 different vehicles towing with an Allegro Bus. I wanted progressive braking and no intrusion into the RV''s braking system. The panel indicator in the RV provides information and adjustment of the amount of braking
of your toad, as well as the indicator that everything is still connected properly.
Wired thru the 7 position tow plug with a battery charge lead the toad battery doesn't run down. The hookup is simple with just the one wire from the coach and the break away emergency cable.
