Anybody with dual batteries?
Just want some ideas. I really don't want to buy optima batteries or odyssey. I was thing on fabricating my own battery shelf and add a small gel battery just for my off road lights and future add ons.

Future stuff
2 more 9 inch light bars
40" light bar
Rocklight
Bed lights
1600 watt peak amp
I can't tell you what all the is going to draw unless I start doing the math but I know it's just going to be a little too much for my 110 alternator. I pick up a HO alternator already I've yet to put it in. The truck is also going to be a mud truck one day so I'll add a winch probably in not saying I need another battery because I'll drain my current one, it's really for security so I know I can put all this **** on and not worry about leaving something on for too long and come back to a dead truck

NIGHT TRAIN
following...
i am converting from a CAI with filter on drivers side, to a centrally located filter centered under my hood scoops. when this happens, i will have a nice spot for a 2nd battery where the CAI filter used to be.

OK...granted that's a lot of LED stuff, most LED bars don't actually pull as much current as they advertise. In other words, they aren't as bright as they say they are.
That being said, with everything you listed running at the same time, as a worst case scenario, that would put a ton of strain on your alternator, which I doubt would would be able to keep up.
My suggestion is to upgrade to a 200a alternator, and Google the "Big 3" upgrade. This involves upgrading the cable from the alternator to the battery, and the ground cables from the battery to the frame, and the frame to the engine block. This will be way more expensive than adding an extra battery, but it sounds like you probably have some extra cash to play with.
Simply adding an extra battery will improve capacity, which will work. But I feel like you'll be replacing batteries left and right...possibly alternators as well.
