Best thing to do

here is a get a few peoplre and have them listen to various parts of the truck to see if the noise can be pin-pointed.

Somewhere in there you have a vacuum resevoir that is dumping after the vacuum drops below a certain level. Might be hard to find but I'd start by checking out the heater controls. I think they are all vacuum operated on that year rig.
