Thinking about SMI Aireforce One-Question

Hello everyone,

I am thinking the SMI airforce one however I have spoken to two RV dealers about instillation and both of them told me that they do recommend any braking system that taps in the coaches air supply.

Both of these dealers are in the Albany, NY area. I wonder if there is some regional lack of knowledge on this product.

I would like to get some input on this.

Thanks,

Stuart
