Gassing
Do flooded wet cell batteries only produce gas when being charged? Can they be charged outdoors and then placed inside a camper for use powering fans, etc. safely?

Are you saying that they only give off gas when charging and in fact at higher voltages?
Not exactly.
They only give off enough gas to be a problem when being charged at a HIGH rate.
At normal charging rates, the small amount of H and O generated will not cause a problem .......unless maybe there is a spark or flame within a couple of inches of the battery.
Once dispersed, neither H or O are dangerous.
If charged at a REALLY high rate, so that the electrolyte actually boils.....then Sulfuric acid fumes can be dangerous.
Best to use AGMs inside. Next best is sealed wet with a reasonably sized charger. Last is open wet with a small charger but that option really is not recommended.
