What do you guys do with this after you relocate the battery?
The cruise control won't function very well without a vacuum reservoir. It doesn't take much throttle at all to get really low vacuum or positive pressure, and the cruise will back off. Someone posted awhile back that their cruise works "just fine" with it removed. I don't believe it.
If you drive your truck long distances, and use the cruise to keep from getting caught in speed-traps, you need a vacuum reservoir. If your truck is always on jack stands, or tends to break before you get very far anyway, you probably don't care about cruise operation.
