OK - I still think the marketers of these devices are doing a great job confusing people with the requirements for towed trailers as opposed to towed vehicles. I know that based on my experience with RV's since the late 80's aux. brake systems are definitely not used by the majority of motorhome people towing cars. I suppose once I spend the dollars necessary for a system and go through the trouble of installing it I will become a big proponent of the systems also due to this investment. I can see that it could help minimize liability.

Anyhow, I trade cars often and do not want to make expensive personalizations to a tow car and I am not at all excited about someone tapping into my air system. There is more than enough leaks in a prevost air system without adding another joint.

I guess with the above in mind is there a brake system that I should look at?
