We retreat inside our RV and use physics by slightly pressurizing the interior so that no generator fumes can enter.
You still need air coming from outside. Filters on RV systems are not what people might think. To filter the fumes out, a filter has to be at least 12 MERV rating, it's a bulky cartridge. You can find it sometimes in HVAC systems of upscale buildings or hospitals but not in RV.
