Pickup truck GVWR vs axle ratings - don't add up

IF your two axle ratings exactly equaled your GVWR then you could essentially NEVER use the entire GVWR because you'd have to load things so that each axle would be maxed out completely which would be nearly impossible to do. Axle ratings equal MORE than GVWR which given you the flexibility to actually USE the GVWR. GVWR ratings by DOT take into account many more items than just the axle rating, including things like engine cooling, braking, transmission and or clutch capability etc.
