Question:
For long term or winter storage, should you let the air out of the bag?

There's no inflation/deflation maintenance schedule for the air bags in the Trailair Flex Air pin boxes like the # LC328492 that you referenced. Whatever PSI rating your towing setup requires can be left in at all times. If you prefer letting air out when storing the trailer don't go below 5 psi though as this allows the bag to hold it's shape.
