The large cells and high capacity as a wet battery gives you enough sustained power to use without much concern for dry camping.
However, unlike agm's, you need to keep these charged regularly to keep fresh.
Anyone I know making this change will not go back to just one 12 volt battery because of such a dramatic difference.

I started out with two 12V Interstate deep cycle. They didn't do very well when we dry camped.
When I installed the solar panel I switched them out for two T105 Trojans. Made a big difference. I just wish I would have gotten the T145 Trojans.
I checked out the Optima at that time, but they didn't have enough cold cranking amps.
I don't know how the gel batteries compare to the Trojan deep cycle.
