Vibration between 45 and 60 mph

[Mike5150]

I'm having an issue with my 2022 Ram 2500 4x4 with the 6.7 l cummins engine. The rear end jumps when I have a trailer attached. Also I'm getting a vibration between 45 and 60 mph . The dealer says they haven't seen this before.
Any help would be greatly appreciated
Thanks

You would probably have better luck on the HDRams.com forum. This one is for the 1500s.
