The speedo input comes from a sensor mounted in the top center of the rear differential, probably your culprit. Either wire broken or disconnected. They will also accumulate fine metal particles (the sensor) so you might remove the sensor and clean the tip, it is magnetic. bg

Replaced that sensor thinking the same thing, wasn't that problem. Turns out our dog did it she ate the rear wiring harness including my new rear camera from edge. Camera shared power from the ABS key on fuse, so one blown 10 amp in slot 35 created all this mess! Problem solved!
Thanks for all the feed back, an honk if you see 2 Rams, 1with 5th wheel, other enclosed trailer with two SUVs following. We will be on 75 South bound in a hours.
