This is all such BS. I went to the Pa DOT page http://www.dmv.state.pa.us/pdotforms/vehicle_code/chapter13.pdf and go to page 5 to 1304 f and 1305 a. The DOT doesn't even know their own laws. Trucks may be registered with the GVWR and may also be reguisted with the CGVWR in "f" and then below in "a " it states it can be registered as GVWR OR CGVWR. So here it is in writing and these people are just on a power trip. You will notice it is required for Truck Tractors to register both ways, not pickups.
