I'm working with a dealer on a new 2021 3500 limited that's still in transit to the dealer. Has pretty much every option, 90k MSRP, but there's not mention of power deployable running boards (or any running boards) on the window sticker or invoice. I've been shopping for a while and have never seen this, and the dealership seems confused too... Is this a thing or do you think it will show up with running boards?
