I'm looking at new '24 3500 Cummins HO Mega Cab Limited trucks with rear air, and it seems the Power Deployable Running Boards are not available. Is that really true? I have the factory power running boards on my existing '21 Crew Cab and gotta have them on anything new for my wife's bad knees. I looked briefly at the AMP site and it implies that their kit won't work with these trucks.
