2 air flappers
I have two (2) tanks underneath the rear of my Minnie Winnie just behind the bumper that have what appears to be flapper like attachment that might let air out?? Any idea what these might be for, noth...

This a really wild guess, but the OP's RV tanks may be somehow warm-air heated by the RV's propane furnace. The flaps MAY BE for letting the warm air exhaust to the outside after it has circulated around the tanks.
