Every time going over GVWR gets discussed, the scare tactic of "you can get your house sued away" shows up. I'm still waiting for one such real life case where someone under GAWRs, but over GVWR, gets sued in court. There're much easier fruits for lawyers to pick on.
Personally, as an engineer I'd love to sit in such a trial as expert witness. I'd go up an entire team of OEM engineers, and ask them to show how someone under GAWRs but over GVWR could have caused the accident. But somehow if the were under GVWR the accident wouldn't have occured.
Food for thought, ever wonder how commercial haulers can suddenly, legally, haul a Cat D11 once they buy an overweight permit? Suddenly, every GVW/GCWR (not that semi tractors have those to begin with) + laws of physics gets thrown out the window with a government issued piece of paper?
What if I bought an overweight permit for my Ram 3500, then can I go over my GVW/GCWRs? Would accidents be magically avoided?
