Brake Buddy Vantage Select -
BrakeBuddy Vantage Select | BrakeBuddy - Braking systems for motorhomes towing a vehicle
This has proportional braking, adjustable braking selected by the driver in the motorhome, and provision for break-away braking.
It is easy to set up.
I have been towing the smart without using a braking system on the car but do have this Brake Buddy which is yet to be used. A braking system is required in many localities and most require a break-away system.
Since the car is very light it doesn't need to have it's own braking when towed by a motorhome. The only reason to use one is to be legal, and to have the security of braking on long downhill stretches and if the towed vehicle breaks away from the motorhome. Reason enough, I guess.
