I spoke with an exceptionally well-rated expert auto upholsterer here in Florida yesterday about this. My hope was that I could get this repaired permanently rather than fret future value of my 2021 Limited.
She confirmed that repairing/replacing the leather is no easy task, and expensive. She added that they don't do dash work because of this. The windshield typically has to come out, which adds cost to get the camera recalibrated, and the labor, skills, etc. make it not worthwhile for them. She hasn't heard of this issue lately with RAMs but she hears it all the time from BMW, Jaguar, and other luxury vehicles with leather dashes. She suggested trying a place that does car restorations. To me, that sounds like even more cost.
This truck is awesome, but faced with a receding leather dash and the just-now-emerging bubbling of my hood paint, it's time to trade it in for something else rather than see its value decrease considerably.
