I believe what Carl is referring to is in the Keystone Montana Owners Manual Page 24.
See for details. You can download it from Keystone.

You torque the lug nuts in sequence (star pattern) and to a sequentially higher torque level for each stage.
Wheel lug torque:
** 1/2" STUD is 110-120 ft/lbs. MINE
9/16" STUD is 140-150 ft/lbs
NOTE: The NUT on the 1/2" STUD takes a 3/4" socket!!!
I noticed my lug nuts are stenciled.
As for the knuckle dragging gorilla over torquing the lug nuts, long time ago I had my tires balanced and rotated. Sometime after that I got a flat. When I went to remove the tire I broke 3 studs off. They had been over torqued.
The last two times I balanced my trailer tires, I used the hydraulic system levelers to raise the whole thing up. Block the frame, then pulled the tires and took them to the shop to get them balanced.
