Truck GVWR wrong weight listed on registration

The theory of having insurance is they assume the risk that the insured individuals property will be damaged or destroyed, as well as the responsibility for any act of negligence, ignorance, or stupidity on the part of the insured. The things they do not cover are specifically listed in the policy terms.

If they could get out of paying by showing it was the fault of the insured, they'd never pay a claim.
