On the question of two 6vdc batteries in series vs 12vdc batteries in parallel, i have posted on this before in length.
But the short of it is that two 6 volt batteries vs 12vdc batteries is a wash except two 6 volt batteries will last longer (life time) due to larger plate size.. Life of 6 years versus 4 to 5 years.
Two 6vdc batteries require an extra cable and if a cell goes bad on two 6vdc in parallel, then you have zero voltage output vs two 12vdc batteries in parallel where one of the 12vdc batteries would still provide 12vdc but at 1/2 capacity.

Thanks
Excellent summation!
Thanks.

I would suggest you find out what power converter you have and read up o how it works. Since you have a new unit, you most likely have a converter that will automatically change modes and switch to trickle charge once the batteries are fully charged - meaning they can be left in charge mode indefinitely. But you should check your manual to be sure since this is something you definitely need to know and understand. Once you have read it, you will be able to know what mode it is in by taking a quick voltmeter read with the power converter on (shore power or generator on). Different voltage levels reflect different charging modes.

Hopefully you have a Progressive Dynamics unit.

Will just rarely go in trailer at home to clean and stock, but will have power with plugged in.
Simple, if the camper is plugged in to shore power, leave battery disconnect in on position

If no shore power, disconnect battery to keep converter from draining battery!

Trailers we've had with 1 12v battery have not lasted very long being plugged in during camping season. In 2008 we bought a trailer had 2 12v battery's installed, they are still in use in their 3rd trailer.
