Batteries--Changing from 2x12v to 2x6v
I'm planning on switching out my two original 12-volt batteries to two 6-volt. My question: Currently with the 12v in parallel, there are 3-4 cables hooked to the positive terminals of each battery. ...

Hi,
I guess it matters how you number the batteries. I always call the first battery the one that the negative terminal is on to ground and the second battery the one that it feeds.
So battery #1 in my drawings would be - 6 volts to ground of your RV. Then the +6 volts is connected to the - 6 of battery #2. Battery #2 + terminal would be 12 volts above ground, and where the wires now connected to your + 12 volt would terminate.
Think of a pair of golf cart batteries as a 130 pound 12 volt battery in two easy to carry halves - 'only' 67 pounds each.
So why change the battery now? With winter coming, unless you plan on camping, it would be much better to wait until about 1-2 weeks before a upcoming trip to put in the new batteries. If you plan any winter camping, then the golf cart batteries will extend the time between running the generator - especially helpful if you need to run the furnace a lot.
There should be a cable between the two + 12 batteries of your current set up. Look for it, and save it. You would be able to use it to connect the +6 of battery #1 to the -6 of battery #2.
Good luck,
Fred.
