Don did you ever find the VDR? I am having a air pressure issue the rear air gage goes from 0 to 150 when it is cold and stops when it warms up. The VDU is not under the bed(slide out) as freightliner said and I have looked around the engine, no luck. I have the same unit as you I have a 2002 Itasca Horizon 2 slides and it is 39.9 long. thanks
According to both Freightliner and Winnebago, the VDC/VDU is usually mounted somewhere in the engine comparment. Mine was mounted on a forward bulkhead just under the forward engine cover. It was facing the rear of the coach so it was not easy to see immediately.
You can call Winnebago Service Administration, give them your coach serial #, and they will tell you exactly where the VDU was installed.
