Battery replacement
I need to replace the batteries in our travel trailer. I would like to know if I can replace 2 12 volt batteries connected in parallel with 2 6 volt golf cart batteries connected in series. I need to ...

As others have already pointed out, two GC2 type six volts batteries are superior to two 12V batteries in almost all aspects -- except price.
Not true. :W With dual 12 volts one can choose to run them in parallel together or sequentially, drawing one down to ~ 50% capacity then switching to the second whereas dual 6 volts both have to be in service all the time to be useful. Secondly, 12 volt jugs generally have less internal resistance than six volts and as a result tend to suffer less voltage drop under heavy load from an inverter than do 6 volts. If there's any notable advantage to 6 volt batteries it's in size because they typically have a footprint similar to a G24 12 volt but are taller, often making them easier to install in a tight location where a pair of G31 12 volts just won't fit. It isn't just price alone that dictates the difference, many do prefer to run dual G31 12 volt batts which are similar in capacity to a pair of 6 volt GC2s. :R
