12V or 6V Batteries - Which charge Better?
I plan to switch to two 6V batteries in series, but before I do, I need to ask this question. When the batteries are drained and in need of charging, which will charge back up to full FASTER? Two ...

The above comments raise an interesting question: Is there any performance difference between using two 6V wet cell batteries versus using two 6V AGM batteries in an RV?
I am actually answer that with specific experience.
The answer is YES. Can You afford it is another question.
Before the depression, I did a massive re-fit on a performance cruiser and the owner wanted to keep his existing house bank, but charge it more effectively. We did that (and some other things) and it all worked as expected. It worked well for a month and then a cell shorted. He (the owner) had a friend that did UPS stuff. Said friend got him a deal on a pair of AGMs with similar package and rating. The owner immediately reported shorter charge times at higher current (we had installed a very well instrumented charging system) and also longer run times before the low voltage threshold. This was interesting as we had not yet corrected the alarm for the AGM.
