A "proper" battery tender will NOT charge at a fast enough rate to "gas" the batteries in any significant amount.
Then, it is doubtful that the RV is really sealed good enough to promote accumulation.
And what ignition source would there be ??
You doubt the RV is sealed good enough???? Maybe not to your standards, but corrosive Gas will just accumulate and corrode out everything inside that toyhauler garage. Lead Batteries OUTGAS. How much depends on the charger you are using. A proper Battery Maintainer will not outgas. There is a reason that good Battery Minders cost a lot MORE than the Harbor Freight cheap ones. Doug
PS. You ought to see the corrosion in some Motorhome Coach battery compartments that ARE vented thru the bottom and back wall of the compartment.
