interesting about Pa. - when we lived in the shenandoah valley (of virginia) i ran thru Pa. many times in my crewcut long bed f350 and never stopped at any scale, even when towing trailers/cars.

according to some -

The weight limit for having to get weighed in PA is 10000 pounds (5 tons).


PENNSYLVANIA
Regardless of size, the following vehicles are subject to inspection and weigh station examinations: (1) agriculture vehicles when using public highways; (2) passenger and specialty vehicles towing large trailers; (3) large recreational vehicles, and (4) trucks.
