Please do not throw rocks at me but the information I seek is so secret no company will revel it for "liability" reasons.
*Bought a trailer hitch for said 2009 Dodge Grand Caravan with Sto n Go but cannot find anywhere what to torque the bolts that hold it to the frame to. Nothing came with the hitch by way of instructions.*
*If you guys can't help I'll just snug 'em up with my air gun to just over 100 ft/lbs??*
*Thanks guys. Remember I've asked more stupid stuff in the past *

Life is too short to hold a grudge; slash some tires and call it even !
Mike,
In a case such as this, the tension (what you really are creating with the assembly torque) is really not important as it is an assembly that you are trying to make seal. The real reason for the tension is two fold. First is that adequate tension will prevent the fastener from loosening with load cycles. The second is that it gets you some free joint shear strength with the inter-element friction. OK??
Now, all that said, if you dig around on the web you can find tables for maximum torque for common fasteners by specification (size, pitch and grade). If you don't want to trust a good reef on a wench, use the table.
Me, I'd just pull on it till the lock washers go flat then a little more.
