You have a good way of looking at it. If everyone was like you the engineers wouldn't have to design huge safety margins into everything. Guys like me operate in that safety margin quite regularly. We bought our Kenworth with full intentions of loading 70,000 lbs on its back (14,000 lbs over its GVWR). It doesn't seem to bother the truck in the least. (We only use the truck off road)
