Pin Box Bolts torque
I want to raise my pin box up and need to know how much to tighten the bolts with my torque wrench. I think they are 1/2" but I don't know the grade. Thanks

My Lippert frame manual on our 2014 Bighorn recommends that the pin box bolts be torqued to 110 foot pounds.
After taking delivery from the factory on an ordered new unit I checked the pin box bolts. Out of ten bolts, eight were less than 110# torque. Five of those eight were lower than 75# torque.
I hauled the RV from Maine to Florida then on to Arizona, about 3700 miles, where I rechecked the torque. Eight of the ten bolts were at specs and the other two bolts were within five pounds of factory specs (110#).
I rechecked the torque after arriving back to Maine (4500 miles) and found all bolts were at 110#.
