Fuel hose leaking

You know what is weird regarding fueling up is when it gets really cold. We took a trip to Texas a couple of years ago in December and as soon as we had to stop and get fuel it would only let me fuel about 30 seconds and then kicked off the pump...had to keep doing that for about 20 minutes to get just 10 gals. It was around freezing. Talked to some locals and they said that happens sometimes. I did some googling and found that this could be an indication that the valve for the fuel vapor system could be frozen or bad. So when we got back to CA I was all prepared to drop the tank to get to the valve and replace it. BUT it has not happened since. I will say going out in the RV in freezing weather will not be happening again. We even had our water hose freeze...it was nuts. We only went to Dallas to see our daughter before White Christmas...she is a Broadway actress and we follow her career.
So when it comes to fueling these things do not like the cold.
