Well if you are just going to change the dials/knobs...note that an instability 'might'
manifest itself when raising the ball/tongue...go back to a slightly nose down
as you have right now
You are fixing something that seems to not be broken...
There were a few other threads from both newbies and an old timer who asked and
they went into this mode...re-dialing it in without knowing the goal...
Meaning do you know the why of these adjustments? It's not just for
the looks, but for some change and benefit to the handling of the setup
that these adjustments are made
They added/removed links, tilted the head both back and forward, changed bar
ratings, raised/lowered the ball/tongue, increased and/or reduced weight off their
TV's front axle and a big ETC
Good luck with the knobs...
