I've got covered parking for the Sovereign, so the only time it will be in the sun is on "real" camping trips. Also, I have not as yet had an opportunity to use the gas burner on the Dometic reboiler - due to the definition of "camping" by "She Who Must Be Obeyed" I will forever be relegated to camping adjacent to a 110 volt plug in. Therefore, I do not think there will ever be any gas exhaust coming up the flue.
Good point on the temps, though.
All the better reason to make sure all of the bottles are cycled and emptied on a regular basis to make sure none exceeds it's "proper age of maturity".
Anyone know how many weeks a bottle of Mogan David 20/20 or Boone's Farm should be good for?
