I searched through the library, and could only find how to adjust after it's install, not the correct way to install.
Searching online, I could only find instructions for their newer products, not the older. "Measure from the mark on the ball coupler to the center of the cam arm pivot bolt" ~ Reese Install Instructions for the newer model. So I'm thinking that there's a like measurement for the older.
What I was trying to show with the picture (and I now see I forgot to mention) is as close as I was able to follow the instructions without a measurement and where the arms are "seated" and it looks dangerously close to the ground.
edit: BTW, I did the library search, and all other searches, before I bothered you guys.
