You must realize GVWR may be set lower to accommodate marketing segments or commercial use. Identically configured trucks can have different ratings (many examples have been cited before). Diligence in researching and configuring your purchase can give you more capacity than the numbers reflect.
If you read any of "Title 49 CFR 571 FEDERAL MOTOR VEHICLE SAFETY STANDARDS," GVWR is all about braking capacity as well as the capacity of tires and rims. I have not found any other listed safety requirement for GVWR.
It is what it is, and I think it would be unwise to presume otherwise.
That would be the maximum allowed. That does not mean the oem's are rating their vehicles all the way up to this standard.
Okay, now I get what you're saying. That's the reason there is the GCWR. When there is the possibility overloading due to a vehicle's high GVWR and GAWRs, the GCWR's comes into play to prevent the potential overload and/or over taxing the powertrain. Example: A Ram 3500 with GVWR of 14,000 and the rear GAWR of 9,750.
From what I understand, RV Tow Check calculates both GCWR and GVWR (available payload) and responds with the lowest towing capacity of the two. It's a double check method to ensure no rating is overloaded based on 20% PW and 12.5% TW or the GCWR. But there is this statement too: "Never tow more than the manufacturer's published rating found in the vehicle owner's manual."
