Only you can determine your power draws. There are calculators that can help but for me in use is the best way.
115w may cover you on a daily basis but get a few cloudy days and it will have a heck of a time charging up two 6v that are discharged. There is a formula that suggest 1-1.5 watts per AH of battery capacity. With two 6v, you are looking at 200w or more.
With your described uses, a pair of 6v and enough solar, I don't see you needing a second set of 6v at all. Add in that discharging a battery and letting it sit like that is a horrible thing to do.
We used a 230w panel and a 95 ah battery to power the trailer last year. The way we went through the power you would think there was a cord coming out of the woods some where. We use the furnace nightly and sometimes in the day too, light the rig from end to end, watch TV/DVD, have music, run the fans, etc. without a thought. We take a generator for air conditioning and as a back up but haven't needed it since we got the solar. The 230w system we used can be put together for around $400 roughly.
