Good morning All,

I have been traveling and am just now getting back online to look at these posts.

Here is what we found with the "Air Force One Air Brake" system. They mounted the Air tank, small version of the Prevost tanks and a valve near the D/S rear tag wheel up under the frame attached near the U shaped tunnel for the drivetrain shaft. When the Prevost leveling system was air was dumped the fitting between the Air Force One valve and the Air Force one tank caught on the corner of the Prevost frame and snapped of the valve at the fitting to the tank. The noise that I heard was the air in the tank evacuating. What I could not understand is why my main air was acting squirrely, not running up and dropping off quickly. I ended up having to replace my dryer in this process as it would not blow off at full pressure after this event. It might not be related but it was odd. The bottomline here is that the Prevost equipment and placement has been engineered carefully and with all of the potential pitfalls in mind. I am afraid that this is not the case with others, as there is not enough experience with our heavy complex units. Mine ran great out of jacksonville to San Antonio Fl. but I have to say that there is a large ????? mark in the back of my mind about the future, rocks, whatever. Hope I am wrong and am sure that the folks at Air Force One will be carefully looking into this and will report back to us online to give us a first hand assessment.
