Suggest you familiarize yourself with the goal of all these dials, knobs
and adjustments...
The goal is to have the setup as close to correct for 'your' TV & trailer
TV manual will tell you how much to WD from the rear axle over to the
front axle. The old rule of thumb no longer applies, as the TV OEMs
have vary different suspensions these days
Some will say return front height to what it was before hooking up. Some
will say to get withing 1/2" higher, etc, etc, etc, etc
The trailer tongue should be level at it's highest pointing and I
prefer pointing slightly down
Unless you know the loaded trailer tongue, you will only be guessing
So best to go out and weigh the setup axle by axle. WD tensioned and
untensioned
Then know what each dial/knob/etc adjustment does and what for
Have seen newbies and even some old timers go in circles to find
that their tongue weight was really much too low/high and/or that
their pointing was too high all along
Good luck
