Whatever it takes to have your trailer level at its highest pointing...I prefer pointing slightly down
That the TV's front axle is re-loaded as per your glove box manual. Used to be even drop front and back, but today's TVs has many different architectures (IFS, Live Axle, and bump stops that touch 100% of the time, etc)
Most likely you will need to readjust the shank...if it has adjustment holes. Some times flipping it if it was sticking up
That is the goal....all of the adjustment recommendations are just the dials/knobs/etc to get to that goal of a level trailer, or pointing slightly down after it is dialed.
