Sorry but this is WRONG.
The trailer is NOT part of the GVWR of the tow vehicle just the tongue weight.
If you go to a scale the weight on the tow vehicle axles is the GVW, the weight on the trailer axles is NOT part of the GVW of the tow vehicle.
GCVWR (Gross Combined Vehicle Weight Rating) includes the trailer.
