I haven't studied this near as much as you guys but I see those hot shoters everyday pulling 3 car/trucks. I don't even have to do any math to figure that might be over the mfg tow ratings. However in Ohio non commercial doesn't get scrutinized like in some other states. But I've mentioned this at least a dozen times anyone who has ever attended a tractor pull or local fair has to have seen what comes in on SRW trucks pulling goosenecks. I know this doesn't make it right or legal but guy down the road has a business and he pulls way more than I do behind a 3/4T dodge cummins SRW. Has for years.
The thing I can't believe they haven't cracked down on is the reason everybody wants to use a 3/4 or 1T truck is to get by without paying the high insurnace and tags. Heck most of the time bigger trucks can be bought cheaper.
