Sometimes I think you guys just like over complicating things for the sport of it.
While not as clean, why not just take the easy route and loop two chains through the "A" of the tonge and connect them via rated hardware? Or are we assuming the tongue triangulation is too far away or ripped off in the accident completely?
I'm not sure why you guys are dogging on quick links, some of them ARE rated and are even supplied by Reese as a product intended for towing.
A rated one:
You rip through two of those, and you likely rolled your truck in the process.
Or, if you REALLY want sturdy, use these: http://www.westmarine.com/webapp/wcs...classNum=50333
You can find those cheaper than west marine, but good lord, 6,500# per link should suffice.
