Also notice the two front floor ducts are not putting out heat with the right side furnace running.
See the sig. below......our coach may be similar. The front (right side) furnace uses the same t-stat as the A/C.......just move the selector switch to the far right (gas heat).
The rear furnace is controlled by a small t=stat on the wall in the bedroom. There is an ON-OFF that is a part of the t-stat but on the bottom side of it.
