I can find no mention of stopping as the only criteria in any GVWR definitions that I can find. I still say it "should" be the maximum weight a vehicle is safe and comfortable with. I feel that my 9,200 pound GVWR rated pickup is good up to 9,200 pounds, both going, stopping, and steering. After that????? If GM caught me with a burned out transmission and broken frame while loaded to a GVWR of 12,000 pounds, I don't think they would tell me I was simply overloading the brakes. Point is, they rate the whole truck, not individual parts with the GVWR.
