Hello Brian, thanks for reaching out. Some RVs including Freightliner do come with the components for the Demco Air Force One brake system pre-installed, and it sounds like this is the air brake fitting you are describing. This can be utilized but not for the Roadmaster BrakeMaster system. It will only work for the Air Force One system and for that all you will need is the following:
- Second Vehicle Kit for Demco Air Force One Flat Tow Brake System # SM99209
The video below will show you an example of installation. Give it a watch and see how you feel. This can be a DIY install if you are familiar with working on cars. If this falls outside your area of expertise then it will best be done by a professional. The link below will show you our installer locator. Just enter your zip code and you will see the full list of installers in your area.
