When compared to true GPS speed, my DS speedometer read 2-3 MPH fast at 65 MPH.
While servicing at Spartan, I had them check and...sure enough...the Final Drive Ratio had been changed, and Newmar was supposed to program the dash to reflect the FDR but apparently got missed.
So, if your Speedo is incorrect, the fix was simple.
