Welcome to irv2.com! RV air conditioners are self-contained, pertaining to air circulation. That is, they re-circulate inside air only, they do not draw in outside air.
I think the only effect your air conditioner may have on odors is how the exhaust vents are directed to project air currents in your RV.
Your coach batteries must be vented to the outside per RVIA standards to prevent battery gas/odors from entering any living space.
Have your physically checked your vent pipes on the roof for any blockage? This can cause holding tank odors to be forced into the living area.
Have you checked the vent/vacuum breakers under the sink next to the drain pipe? They must operate freely to allow water to drain efficiently, but close easily to prevent odors from back-flowing into the living space. If you unscrew them, then gently shake them, you should feel/hear the operation of the vent.
Hope that helps some.
