12 volts to 6 volts; whats the benefit?
So we're replacing our coach batteries which are four 12 volts group 27 batteries. We've heard some say they can get a longer run time off of four golf cart batteries over same number of deep cell t...

You would need room for 8 6V to equal your 4 12V but it's really all about amp/hours so you have to look at what you have and what you would have if you change.
Your math is wrong. GCs would be more than adequate. GCs have more than twice the amphour capacity of 27s. They have the same footprint as group 24, (which are shorter than 27s) but GCs are taller than either.
Group 27s run about 90 to 100 Amp hours each. Four would be able to provide 360 to 400 AH.
The "standard" Golf Cart type run from 220 to 240 AH
4 in series-parallel would provide 440 to 480 AH. 8 GCs would give 880 or more AH at 12 volts.
