Just ordered a 2022 myself, black exterior. Strongly considered doing the red accent package, but couldn't justify the value. I would have done it if I had gone for the red exterior (probably), but even then it would have pained me.
Far as I can tell, Ram thinks that the red dye is 1,500 bucks more expensive than the gray dye. The nice, thick bolster stitching and seat inserts are the exact same, except that some are dyed gray and some are dyed red. Definitely think the red is nice, but strongly dislike the fact that Ram is price gouging for it. My rationale for not getting it is:
1) The gray is still nice, and rating my interior as 9/10 instead of 10/10 isn't worth $1,500
2) I'll use the money for something like a Retrax tonneau
3) Ram should know that the raw cost of switching from gray to red dye shouldn't equate to even remotely close to a $1,500 upcharge
Props to those who sprung for it!
