Can this be correct??? Duster weighed.

I don't remember now what my 67 weight, "suprisingly heavy."

But I DO remember........I drove in one end of our local waste transfer, weighed at the entrance, and again going out the exit end, and there was I forget........60-80 lbs difference between the scales.

I actually talked with the state weigh "guy" and by the time he got done dazzlin' me with techno BS, I had "no idea." Generally, scale tolerance depends on the weight they have to handle.
