You need to determine your drop or rise
So -with both vehicles on level ground
Measure from the ground to the top edge of the hitch receiver on the navigator
Then measure from the ground to the bottom edge of the trailer’s coupler.
Subtract the height of the receiver from the height of the coupler. This is where you will set the WDH. For proper setup you want the trailer level or slightly down. UP is bad.
Attach the spring bars for tension. With that you will need to follow their recommended set up on the vehicle/WDH but you usually measure the front wheel gap with no weight then with the bars and it should move less than X inches.
Or you can hookup the trailer and use the tongue jack to get back to level then set the spring bar on the link that keeps it level when the weight is on. By using the loaded and unloaded gap measure
