While you mentioned tire balance, did they check RUN-OUT with the wheels mounted on the coach?
If not, easy to do yourself: Use jacks to get front wheels off the ground. You are not crawling under the coach, so jack/safety stands are not required.
Use a 4X4, metal angle or similar that you can move up to the tire as you slowly rotate it. You want to check both "front to back" and "side to side" of the tire.
As you slowly rotate the tire, move the "measurer" in toward the tire until it just touches at the part of the tire with the most run-out. While holding the "measurer" firmly in place, rotate the tire slowly until you find the place with the largest gap between tire and "measurer". Use feeler gauges to measure gap. You really want run-out under .035". At .050" you will really start to notice it.
