Monaco Executive 2005 Owner's Manual page 444

Caster Adjustments:
Caster is the fore and aft tilt (toward the front or rear of the motorhome) of the steering kingpin as
viewed from the side of the motorhome.
"Positive" caster is the tilt of the top end of the kingpin toward the rear of the motorhome.
"Negative" caster is the tilt of the top end of the kingpin toward the front of the motorhome.
Setting the caster angle more positive than specified may result in excess steering effort and/or
shimmy. Decreasing the angle may result in the motorhome wandering or poor steering return to
center. The caster angle is determined by the installed position of the steer axle.
