Dual Battery System

I see no winch in your system, therefore, I don't see the requirement for a second battery. Your running a bunch of lights and a CB.
I have a winch as well as a ridiculous amount of lights and stereo equipment. The winch is the only reason, in my eyes, for spending that much money/time/effort into a dual battery setup.
Yes, it leaves room to grow and expand the amount of doo-dads in your truck, but wait until you need it.
Unless you're into expeditions (week long trail rides).

I've had my dual battery setup for 12-13 years now:

Very simple combiner solenoid to put them in parallel when the engine is running with an override switch for jump starting. No monitor outside of the factory volt gauge. Works perfectly and I never even think about it.

check caraudio website like caraudio.com or caraudioclassifieds.com both are great for getting big batteries with alot of AH for good prices. for your set up either a bigger alt or just getting a good single battery will do. ive ran almost 100A of current off a 110A alt and 1 good batt with no issues for about 3 years.
however i would say if you feel a need for an upgrade an alt is always the best place to start. the batts are really more of a reserve caspasity for below 13.0V and when the vehicle is turned off.

I like the Odyssey batteries I run in my 4Runner. I think I got about 10 years out of the first set before I changed them out (still working) and now have about 5 years on the 2nd set:

I've also run a Premier Power Welder 160 amp. alternator for about 13-14 years now, it is still going strong:

Wore out one set of brushes in it about 7 years ago, about time to send it out to get a new set installed.

Second Batt for Winch
I'm new to all this but I want to do it right. So, is a second battery even necessary if all I am doing is running a winch and three 100 watt lights?

I'm running 4 55w hid lights, a 110w radio, a 200w siren, an led light bar, safety lights and on board air, so I'm going to be running the dual batteries, and I'm going to get the Sierra expeditions dual battery controller cause its a pretty nice set up!

im not running all this stuff yet due to the fact that i want to post my build on here, but i want to have everything already set up since im going to be making my 4Runner into an off road race car in Score class 6 BITD 7200. the reason im going to be running a dual battery system, is because im going to have a modified MSD Dual ignition system, so i dont want my only battery to run all my accessories while it also handles the engine spark. i also like the dual system, because if my main battery starts losing its power, i can link both batteries so that i can always have 12.8V which is the ideal voltage for it to run.
