That RV having the Actia instrument panel I'm not sure if it uses the same stepper motors as Chevy, etc. panels. Stim mentioned his being a PU which doesn't have the same instrument panel. The Actias are know to be problematic. They are a computer, themselves. Had issues with mine intermittently resetting while going down the road. Quite a few places repair them.
