Need help on dual batteries for gen II (95LS)

[scrubber3]

Just picked up another battery for cheap and was trying to figure out the best way to run a dual setup on my rig. Any ideas? I want to keep the back open enough for me and my woman to sleep back there. Any precautions I should take, and any combinations I should watch out for? THANKS!!!

Do you have ABS? I don't remember was it standard or option on LS. If not you could fit it in that corner (left rear). You need battery separator as well. Do you have a winch? Otherwise I don't really see much point.

That corner is pretty much empty. no ABS. I will have a winch and a possibly a fridge soon. I'll also have a radio come Christmas. I intend on putting it to use and figured since I have a brand new optima blue top I'd use it.
