There is a third option.
Seal the vent when not flying.
 
I would not recommend this for RV wing tanks.  When I was leak testing my RV-8 tanks, I put a few gallons of gas in them, and left them in various positions to test all the seams.  I sealed up all the openings when I did this, and quickly found out that it will build a lot of pressure.  I recall walking out in the garage and looking in horror at my tank skins bulging outward.  Fortunately, I rescued them before any harm could be done.  I won't be doing that again.  
 
Makes me wonder about cars.  Aren't those tanks sealed, or at least sealed to some pressure?
