Now with a few (very few) trips under my belt, I am trying to figure out some of the systems on the truck.

The "OPT" dash switches are now vexing me! Renegade has plead the need for further research. Two Freightliner dealers haven't a clue. Nothing on trucker's report. I've even been flicking them on and off randomly to see if anything lights up, shuts-down, extends, ejects, explodes, etc! No joy.

Sorry for the lack of a close-up, but please take a look at the three switches on the end of the cluster, next to the Warning Stickers. They are all labeled "OPT", all just on/off, not momentary, and they illuminate when activated. Thanks
