Here's an update: Apparently the parking lot I originally used to take all of my measurements wasn't as level as it seemed
This past weekend we were on a beautiful new concrete pad where I was able to get a true read on hitch head and ball heights. Boy was I off! I ended up raising the ball TWO hole up and adding two washers for tilt. As you can see from my picture I am almost perfectly level on the TT and Van. I think I'll try the next link down the next time out, but I am super satisfied so far!
Lesson learned: Be sure you have truly level ground to work with or you'll spend hours chasing your tail!
Thanks everyone for all your help, it's what makes this place awesome!!
