I'm one of those guys who has an overhead and center console and think it's cool to feel like your in a cockpit. I have the triple gauge set up on my A pillar and will be adding some gauges on top of the dash and/or possibly over head. Just kicking around different ideas I came across a Glowshift gauge (which all my future gauges will be to match existing) that measures the temp in your rear diff. I found this to be interesting and wondered if it was a feature on newer trucks or a "just because" gauge. I would venture to say it's more practical for some one who does a lot of towing/hauling. Does anyone have any insight or thoughts on this. Thanks as always.
