Is it a DSI water heater or just a gas pilot light? (In the 2010 I'd assume DSI but you don't say which trailer you're in.) My gas-pilot water heater is cranky about windy conditions... when the main burner it on it's fine, but wind will blow out the pilot. Oddly, if I leave the whole access door open, it seems to tolerate windy conditions pretty well.
