Any input of thoughts as to whether this is a "tire" issue or a possible axle issue? Also, whenever I level side to side, I always have to put the side in question on a 2" board to level the coach, even on "level" pavement campsites.

does the 2" board you are using span the width of the tread? It almost appears that the edge of the tread is hanging off the board and placing stress on the interior chords.
