Re: Demco Air Force 1

The AirForce1 is similar to Spartan's Safe Tow in that there is a ping tank mounted in the coach.
The box in the towed for the AF1 is a control box.
For non-airbrake coaches, the Stay n' Play Duo is the unit (formerly from SMI and now Demco who bought them in 2017) that has a small compressor in the control box that goes in the towed. The box is quite a bit larger as a result.
