Welcome to the forum !
It is really not that confusing, but can be until you understand the 60,000 foot
view of the 'system'. Confusing if down in rat holes without benefit of the big pix
The setup's orientation should
- Have the trailer level at it's highest pointing, or slightly pointing down (my preference)
- Tongue weight should be 12%-15% range of the 'actual' weight
- The WD Hitch system transfers enough weight from the TV rear to the TV front
- The amount of weight is no longer 'one size fits all', but whatever your TV's manual says
- Washers/head tilt/etc is to allow more WD bar travel...therefore more bar tension
- Numbers of holes on the drop shank depends on how much your TV drops vs getting the TT level or pointing slightly down
- Big ETC, ETC, etc...
Since the TV's rear end will drop from the trailer tongue, the starting
height really doesn't matter, therefore measuring only for the range
it will drop to, then what it will be after tensioning the WD Hitch
system
Post back on how it goes and feel free to PM me
Good luck !
