Hi Brian,
Besides all the normal front end checks, don't overlook the tires and proper tire pressure. A steel sidewall tire and/or too much inflation pressure might cause what you feel. Also, check the front sway bar bushings both where the sway bar mounts to the frame and at the ends where it mounts to the lower A arms. Make sure all four of the rear bogies are parallel with the frame. It is not uncommon for one or more to be bent. Look carefully at the upper A arm mounting bolts to make sure both cam washers are in place and the bolts are tight. Do the same at the lower A arm mounting points but there check for play in the bushings. You won't likely be able to feel any slop by hand as the torsion bar is twisting the lower A arm with enough force that you cannot "wiggle" by grabbing the tire in many cases. Use a jack on the lower A arm right where it mounts to the frame and see if you can observe any movement. Look carefully at the lower ball joint mounts to make sure they ar
e not cracked or loose. I assume you have checked the alignment to make sure you have at least some positive caster and that it is about the same on both sides. If you are unsure, safely jack up the coach, block the frame, remove the front tire, loosen the bolt holding the rear upper A arm and turn the cams so the fat part of the cam faces away from the frame. That will give you as much caster as you can get. The rear upper A arm cam on each side should be in about the same position unless you have had frame damage at some point.

Your suggestion of systematically going through the components is what I will try ....thanks for now
