I think it mostly depends on the ratio between the total cubic feet of air in your bus and the CFM (cubic feet per minute) that your exhaust fan is rated for. If your fan is able to fully cycle the air in your bus once every 1-4 minutes, you should almost definitely be fine. Any less than that, I would be worried. That being said, if you aren't going to seal your heater off from the rest of the bus, I would 100% make sure to add a CO detector somewhere, just in case.
