I went with the SMI Stay-n-Play Duo. I like that it has a dual activation system, it relies on the brake signal from the RV and the momentum of the RV slowing. Without one the braking system doesn't engage. It seemed like a good system and was highly recommended by the local truck and hitch shop.
SMI Duo and Roadmaster Sterling tow bar, all said and done with an added monitoring light run to the coach dash was $3724 installed.
