Thanks all for the explanation, NOW I get it. If only my Argosy had room for two 6 volt batteries. Brian

Thank you all for your comments and questions, I guess I did need to clarify a couple points:
First it does have solar, I am not sure of the ouput so I will be checking this, but I do have digital gauges that show it charging, generally keeps battery between 13-15 depending on position and how it sits. This does charge the battery all day. For day and evening use I also carry a Honda 3000 Generator with me, that I can generally run until generator hours end, at 8pm or 10pm, so I know I have a full charge going into the night. By morning the single 12v battery is dead, from running the heater. This has happend twice in the 4 years I have owned the trailer, replacing the single 12v every 2 years. In the morning I can plug in the generator again, so I don't need to go days on end, just trying to make it though the night.
And yes, to another question, I wouldn't be adding a battery to existing, I would go with 2 new batteries, run in series or parrell depending on best application.

Returning to my question about 6v vs 12v, this is what I have found..

Over the course of the last couple days, I have done some research on my own, and found the following equation, which I believe I also saw in on thread reply.
The numbers can vary slightly depending on which battery you choose..

1 6v Trojan T105 has 225 ah x 2
run in series - 12v @ 225 ah
run in parrell - 6v @ 450 ah

1 12v Interstate deep cycle - 100 ah x 2
run in series - 24v @ 100 ah
run in parrell - 12v @ 200 ah

The 6v run in series, would then prove just as good if not better than 12v. Unless anyone can prove otherwise, I think I answered my own question, and just wanted to share for others following this thread or others experiencing the same issue.
Thank you,

Thank you Idroba, and others, I saw the last few posts after I posted mine, and seems very consistent to what I found as well. Thanks again!
