Serious slow down vibration

I have a 2003 Long Bed, HO Cummins/6 Speed with 4.10's

I was running the interstate today at 65 and slowed down for a work zone. I got a serious vibration much like running over 'small' rumble strips. Once I was down to 55 for the work zone and back on the go pedal, the vibration went away. From then on, every time I would slow down, this vibration would surface during the period slow down. I stopped to pay the toll and from 20 mph down to Zero the vibration was really bad, just like running on real large rumble strips. I dont notice any vibration when coming back up to speed. I am sure without question its coming from the rear of the truck. Differential, Universal Joints ??? any thoughts.

It goes to the dealer under warantee in the morning.
