Thanks everyone for the responses. I have read a few times if the batteries are the same type i.e.: wet flooded that putting them in parallel is ok even with different amp hour ratings. I have also heard many responses like here that it isn't a good idea.
I am starting to think about keeping both battery sets but only hooking the solar up to the trojans and using it as our primary power source. The 2 12 volt batteries would charge when we drive and serve as a back up that would be available when/if the trojans get down to 50%
I can install a switch that allows battery A, battery B or both so they wouldn't connected to each other but both available for power. This would also give me the ability to play around using both and go back to one easily.
I think this will work fine for us. We don't use much power the way we camp. No air, microwave, forced air furnace, big tv's etc.
