Two 6 volt vs two 12 volt run time
I was just informed that two 6 volt batteries would run the residential refrigerator many times longer than two 12 volt batteries. I wonder if this is just hype?

FWIW, my front storage battery/etc compartment that has the 5 batteries in it is approx. 22" X 38" X 96" (8 feet) and is very well OEM vented beside the Tupperware battery container with the vent thru the floor I'd added. Nope, I do not worry about a battery explosion from gassing.
Again, the venting of batteries is not all about you and your situation or about me and my situation.
I only mention gassing of hydrogen from battery charging in that it is necessary and hydrogen is lighter than air.
If you need examples, look at what is being made for venting battery boxes: vented battery box
