I was constantly in and out of the truck trying to align the truck with the plow frame. I took a magic marker and made three marks. The first was a vertical mark in the back of the left plow headlight. The second mark was on the hood near the windshield (only viewable from inside the cab), and the third mark was on the dashboard. When all 3 line up, your dead on. To envision this better, think of a gun with the front and rear sites being the markings on the truck while your plow headlight marking is the target.
