I love my 21 AT4HD. The cab room is large and the ride is exceptional for an hd. The bed has lots of room for my fire gear and tools. I’ve been a volunteer fire fighter for 33 years. My only issue is the rear end metal noise decelerating through 38 to 32 mph. I wish I would have held out for the sunroof models to come out. For me to upgrade now with the same truck and a sunroof is 10k more than I paid in May of 21 for mine.
