The only large motor that runs off the battery is the slide. So, for my motorhome, do I want the batteries in parallel or in series? The only large motor that runs off the battery is the slide.

Can you take an 12vdc to 120vac inverter powered by a 12vdc 8oo amp car battery and charge the same battery with a 12vdc 6 amp 120vac Charger plugged in to the same inverter? like a loop..? I have a question on 12vdc charging systems.

I need a battery box with only two out terminals; one +, and one -. I will have a switch (I assume it will be a dbl. pole, dbl. throw, ctr. off) inside the box. With the switch in one [on]position I need 12 v. out. With the switch in the other [on] position I need 24v. I have done this in the past, but cannot remember how. To charge all the batteries at once, the switch needs to be in the 12v. poaition. In my case, the batteries will be about 8 amps, so huge relays are not needed. How did I do it??

This would give you 12 volts. But you need to be carefull because you run the risk of discharging the batteries unevenly. We've written about this in detail on our post <a href="http://overlandresource.com/24-volt-charge-equalizer-install" alt="24 volt battery equalizer install" rel="nofollow">24 volt battery equalizer install</a> Hope this helps.
