Did we watch the same video? He said the Max Combine Weight Rating
was 19,500 and the Max Tow Rating
was 12,500 lbs but that 12,500 the truck could only way 6XXX lbs or it would exceed the Gross Combined Weight. He subtracted the real weight ready to camp from the Max Combine Rating and come with a Max Towing Rating of 11,500 since his truck was heaver and would exceed the Gross Combine Weight Rating otherwise. Bottom line the Two Capacity is figured by subtracting the vehicle weight from the Gross Combine Rating equals the the Max Tow for your
Gross Combine Weight Rating - Ready to Camp truck Weight = Max Tow Rating of Your Truck.
The heaver the truck the less tow capacity you have left to not to exceed the Gross Combine Weight Rating. Tow rating depends on how much the truck weights if you not going to exceed the Gross Combine Weight Ratings.
Edit -- Max Tow Rating
is achieved from subtracting the base no option truck
from the Max Combine Tow Rating so options in the truck and people do reduce the Max Tow Rating. More you truck weighs the more of the Combine Rating and less left over the RV. The Tow Rating on the website are off just like the payload ratings are figured from a NO OPTION Base truck.

Please tell me where I’m wrong. A truck has a GVWR. The combined truck’s Curb Weight, Cargo and Passengers cannot exceed the truck’s GVWR. A truck’s Tow Rating (Max Towing, Towing Capacity) is the allowable weight for a fully loaded towed vehicle. While in the video he’s backing out the weight of the passengers and cargo on a graphic showing both the GVWR and GCWR but not the tow rating as the OP asked about. He left everything left over as what the truck can tow. However, it’s my understanding that most trucks have a listed Tow Rating. In my case, my Tow Rating and GVWR equals my GCWR. My comment to the OP was based on information listed (on his door stickers and charts) for his truck to indicate that passengers and cargo in the truck determines if the truck exceeds the listed Cargo Capacity and GVWR, not necessarily to determine Tow Rating. If you go by the video, it suggests that you can exceed your listed Tow Rating if you do not max out your GVWR. I personally would suggest against advising someone to exceed any of their listed weights limits. Larry G.
