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?

pnichols,
Right on! Amp hours stored in a battery is amp hours of stored current available whether it be a 6 volt battery or a 12 volt battery and that's no secret at all. Only takes one 12 volt battery to supply 12 volts but it take two 6 volt batteries to supply 12 volts. Thus approx twice the cost for just drawing 12 volt DC current from a storage battery source. Also, you can have 1, 3, 5, 7, or 9 etc batteries in a 12 volt batteries system bank. Try that with using 6 volt batteries!
How many battery DC amp hours one wants to have available at 12 volts determines how many batteries and their size of either 6 volt or 12 volt one needs to have in their system. Also no secret either. Simple as that whther the person is highly educated or not! The batteries don't care at all as they know how many amp hours they have stored whether anyone likes it or not! What is, is!
When a 6 volt battery dies in a 12 volt system, 2 batteries must be disconnected but only one battery (the failed battery) if 12 volt batteries are used. Doesn't matter if it's for the engine start battery/batteries or the 12 volt system of the RV or the inverter power supply. 12 volts systems means 12 volts are required and 6 volts is as good as nothing and won't hack it. Like in nothing requiring 12 volt DC in an RV will work at all nor will the 12V DC to 117V AC inverter nor will the engine even turn over so it obviously will not start. How hard is that to understand? Simple as that too for anyone to understand!!!
I've had both 6 volt DC GC battery banks and 12 volt DC battery banks and will not have a 6 volt one again for so many reasons. What other want, do, or have means nothing to me as it their money spent and they'll live with the results. Thankfully, learned my lesson many years ago and am smarter than to do the same thing over again and expect different results stupidly. Sounds like the definition of "stupidity"? Perhaps some commenting/posting on this thread have never even tried both ways personally but yet say they have all the answers. O'well!
