I just removed two 6v batteries from my fifth wheel rv. I'm going to replace them with two 12v batteries. When I removed the 6v batteries, there was one wire running from pos to pos on the two batter...

Ok, thank you for that info. It saves me from making some sparks. I'll try that.
Just getting one little SPARK will most likely blow your close to the battery IN-LINE fuse as well as two "REVERSE POLARITY" fuses back in your 12VDC Power Distribution Panel.
Try not to 'SPARK' your battery system even for a short second haha...
Its not fun tracking down why you are not getting 12VDC from your batteries when that happens...
In the RV world the BLACK CABLE is usually HOT +12VDC and the WHITE CABLE is GND -12VDC.
In the AUTOMOTIVE WORLD that most of us are used to the RED CABLE is HOT +12VDC and the BLACK CABLE in GND -12vdc.
Since the battery connections are used in both RV and AUTOMOTIVE WORLDS you sometimes find both wiring schemes being used. Just be aware.
When messing with battery cables I always take a picture with my cell phone or mark the HOT +12VDC cables with RED FINGERNAIL POLISH...
When you purchase AUTOMOTIVE items like maybe a JENKINS 12VDC Radio setup they usually come with RED and BLACK 12VDC cables. When you install these in the trailer you sometimes end up with a RED WIRE on TOP of BLACK Wire in the 12VDC Power Distribution Panel... This sometimes makes old timers like me turn over in the graves haha...
