Terrible situation and I feel your pain. With only 5k on the truck, did you even shake this thing down for heavy duty towing? What's the break-in cycle before towing a load, I thought the rear diff was several thousand miles? With only 5k, I wouldn't be surprised if it hasn't even gone through a regen cycle yet, or still on the break in oil change. These factors could all lead to the error. Not trying to kick you while you're down, just making the point that you can't drive a truck off the lot and immediately start towing with it.
