Exactly the same as what exactlty ?
I allow that you might be right but I just don't understand.
Seems to me like the only time this would be true is when the charging source is able to supply WAY more current than a single battery will draw when dead. I don't think that would be true with a 40 amp source.

Few batteries can take even 40 amps of charge current beyond the first few minutes.
OK.....so how many individual batteries will take less than 20 amps when their state of charge is really low ? Because that is the point at which you could charge two at the same rate as one.

No, they don't take a lot longer to charge.
It depends......mostly upon exactly HOW they are being recharged.
I am guessing here a bit but how many small travel trailers that come only with a single battery do you know of that come with a 50 amp charger/converter ? My semi-educated guess is somewhere near to none.
Anyway, I didn't say "a lot" longer. But it could be a lot depending on circumstances.

While extra batteries supply power longer, they take a correspondingly longer time to recharge too. And there are a few other disadvantages to extra batteries too....as is already being discussed.

I would take the money you might spend on extra batteries and invest it in an appropriately sized solar system for your dual 6 V system.
