I got the response today via E-Mail pretty impressive for a Sunday. I'll just paste the thread in here so you can see for yourself.
To answer your question, yes and no. Because your tow car has a constant live brake you CANNOT use anything that does not require a live brake. THe Brake Buddy, any of the Road Master systems and many others ARE NOT SAFE in your car. Some will tell you that it will work this extra part or that extra part but it is still not safe. The AIr Force One will work and it will work well. There are no modifications to the system only a minor change in the installation. I would be gald to discuss this if you want to give me a call. Below is my cell number or reach me at work 800-893-3763.
Thank you for your interest, and please let me know if you if you need anything else.
