- Prevents loads on auxiliary battery from draining the starting battery. It works with all types of alternator. Smaller and lighter than traditional isolators. There are no efficiency losses due to diodes. It allows bi-directional charging from the alternator or from shore power. It reduces the load on the charging system by not connecting the auxiliary battery until the primary battery is charged to 13.2V.

For camping, a small led light bar should be able to run during your waking-but-after-dark hours without needing an additional battery, assuming you occasionally start the car if it's an extended multi-night camping trip. However, a nice coleman lantern may be a better option given the cost of a dual battery setup.
If you are serious about dual batteries, I would strongly suggest an AGM type battery (oddysey pc1500 or similar, as mentioned elsewhere in this thread) and I personally prefer an automatic disconnect, over a hardwired or "manually switched" dual battery setup. I've had good success in the past with this one: https://amzn.com/B00LMGPHW2
Also, there are kits on the market now for jk/jku's that have the same smart isolator in them. genesis offroad has one. The kit is nice, but really, it's the isolator that does all the magis. they just sell you a nice mounting kit that is prewired for easy setup.
This particular smart isoloator also has a momentary switch option where.. if your cranking battery is low and can't start your vehicle, you can press a button and connect both batteries for 60 seconds, effectively jumpstarting yourself.
Manual selecter switches.. I've found I always forget to change the setting, and either.. never disconnect the two batteries when I should, or I forget to reconnect them for charging later meaning one battery is always really low. so I've personally given up on manual switches.
(Since this reads a lot like an ad now, let me just say.. I have no affiliation with cole hersee, other than having a great deal of success with that product I linked. I've run dual battery setups in several vehicles, and this is my personal preference. but like all opinions.. everyone has one, and none of them are "wrong" as long as it works for that person)
A deep cycle battery and a battery isolator. Makes it so both batteries charge straight off the alternator, but keeps them seperate so that you can hook all your accessories up to your secondary battery and not have to worry about draining your main. The nicer ones(such as this) will charge the main battery before the secondary, and with the press of a button will temporarily join them in case your main battery is dead so that the starter can pull from both batteries. You could supplement it with a solar charger as well for longer endurance.
