'21 3500 HO- I get what might be a similar noise. I notice it most when I've been slowing with exhaust brake engaged then lightly get back on the throttle. It reminds me of a lugging powerstroke. Haven't had it to the dealer.

Anybody that bought from Bud Clary have issues with out of state registration? I'm in Indiana but might apply to others. I'm a month out from pick up and they finally sent a packet of paperwork to my local BMV. BMV called me to say they didn't send the Certificate of Origin.
