Air Force One on Spartan Chassis

I'm in the process of installing a new Air Force One Brake System on my 2008 American Tradition. I've completed the installation on the Toad (2012 Ford Edge) and it went very smooth. Now getting ready to install the components on the Coach, and I have a couple of questions for any of you that have personally installed one of these.

1) Got under the Coach yesterday and located my Service Relay Valve etc. which is located in front of my rear axle. The Air Force One instructions call for the new Coach Air Connection Assemble to be installed near Service Relay, I assume to make the 1/4 " connection easy. Problem is there is no room to mount the new Coach Air device. Is there any reason this can't be mounted someplace else that's more accessible? I have a electronics bay with tons of room immediately adjacent to where the service relay is located under the Coach. Will this work?

2) My Coach is on the Spartan K-2 Chassis and the Air Force One instruction call for the Metered Air connection to be undone between the Service Relay and Spring Brake Valve. Has anybody done this on there rig? If so, did you have any issues? Photos of your work?

Just want to get it right? Thanks for your help in advance.

Just a head's up. I was at at the Spartan RV school last year. One of the things they do is go over your coach with you and recommend repairs. There were several coaches that had to have work done to the Air Force One system due to improper installation. I would suggest that you give Spartan a call and get some guidance on the installation. I seem to remember them requiring a separate air tank with additional check valves, so as to not have a negative impact on the air system. I am sure they will steer you in the right direction.

I installed mine several years ago on a Roadmaster chassis. They must of changed some things. Mine had a fitting ("T") that installed at the brake can. From there you ran the plastic hose to the rear of the coach where a small box was mounted near the hitch. The box had a flat four lead connector and the snap on air hose fitting.

I probably didn't help you much, but I have a couple of suggestions. When I ran the air line from the brake can to the rear of the coach, I covered it with the plastic electrical split wrapping to protect it.

They also have you mount the piston on the brake pedal and the secure the small cable to the floorboard with a self tapping screw. I didn't like this and drilled through the floor and used a bolt with a lock nut. I also ran the optional indicator light to the dash. It's nice to know that the brake is working.

I'd call SMI. They have good technical support. We called them when I helped my friend install an AF1 on his coach a couple years ago. It was a FL chassis.
