I never worry about fueling either the car or motorhome since i'm using a very short hose and working under a canapy. When the tank truck came to fill the propane tank he pulled out close to 30 feet of hose to reach from the truck to the tank. I was just worried (undoubtedly unnecessarily) that it would give opportunity for moisture to get into the end of the hose if it happened to be raining.
But thankfully it had just stopped snowing when he arrived this morning. Boy is he fast. He blocked his wheels, hooked up the hose, pumped 13 gallons of propane, reeled the hose back in, unblocked his wheels, I paid him, and he was gone in probably not more than 5 minutes.
I do appreciate the responses as it made me feel more relaxed just in case it was really storming. And I'm sure he wouldn't want to come back later either.
