Toyota Repair: vibration in 05 Tundra, driveline vibration, steering wheel

Question
At 1250 miles on new 05 Tundra V8 I noticed a harmonic vibration. This can be felt throught steering wheel, floor board, doors, headrest, dash.  Basically everywhere.  It is there in drive at idle speed or any speed I drive. The smoother the road the more noticable it is.  It is enough that after a few miles of steady driving my hands tingle. Dealer has checked it and says there is nothing they can do.  Any help or suggestion would be greatly appreciated.

Thanks in advance,
Robert

Answer
That doesn't sound right, try taking it to another dealer, by the way was it purchased brand new or as used, I know it's very low mileage but I still need to ask.
It sounds to me that there is a driveline vibration, get another opinion, this just doesn't sound right.
