I understand that it is even against park regulations to pass gas in the night, if you have eaten meat for dinner.
However, I believe RV'ers can get a "RV Flatulence Permit" if they sign a document stating that they will not open the RV vents, windows or doors until one hour after sunrise. Your RV will be sniff tested by random night patrols.
