I took my furnace out and took it apart to fix a problem it had. Based on the design I observed I think that it would be very unlikely for an outside wind to be able to push exhaust gasses into the motorhome. Of course nothing is impossible.
So to help out hopefully you have an LP detector (built into your LP cut off switch probably), smoke detector and carbon monoxide detector installed inside the coach to warn you if lots of exhaust gas getting inside. After all it's not just the furnace that makes exhaust gas. While driving down the road you could get exhaust gas from any LP things that are running or from the engine or the generator exhaust.
I bought a two-pack of onelink wireless speaking smoke and carbon monoxide detectors at Home depot. I installed one in the front and one in the back. If either detects anything they both go off (they're connected wirelessly) and they say what the problem is.
<WHOOP> <WHOOP> <WHOOP> CARBON MONOXIDE DETECTED EXIT IMMEDIATELY <WHOOP> <WHOOP> <WHOOP> and then it repeats.
