NO Mr Smith.. . 2-6's are the same as 1-12. The only difference is you have more amp hours in the 2-6's and a greater life span.. The 15.4 volts you are looking at is for EQUALIZING only... normal charge rate is 14.2-14.6 same as with a 12 volt battery. YES it will take longer to recharge 2-6's but that is what you put up with for the longer life and better holding capability.

This would include the positive and negative wire runs, but not the ground path that travels though the trailer frame itself, if the frame is used for the ground. I can't imagine loads really that high. The wire between the two batteries can be of the same gauge. If you anticipate huge current draws, using an inverter, or have really long wiring runs, you should go to 4 gauge wiring. Otherwize don't worry about it.
In a nutshell, This is the best advice I could offer as well.

(in 20 years of camping, I have never had a battery fail and I've not considered it such a risk that I would bring a spare...and I am a belt and suspenders kind of guy....not that I actually WEAR a belt with suspenders of course...I don't even OWN a pair of suspenders anyway...but I guess I could use jumper cables if I had too....)
