Diesel: Dual Battery Setup

[Beowulf]

For either the Gladiator or the Wrangler, what are the options for running dual full sized batteries?

I saw something for the wrangler that put a battery back in the spare tire cubby.

Is there any room to put two batteries under the hood of the 3.0?

I'm trying to find the same thing... bought a gladiator today that I will be taking delivery of tomorrow and while it's getting the top painted, tinted, xpel'd, etc -- I'd like to figure out the dual battery situation. Sounds like it's not possible (yet). I'll poke around and see if there's room once I have it.

Genesis Off-road is the only dual battery setup I’m aware of.

Sadly, it does not fit the diesel:

I'm thinking a DIY solution is the only solution...hopefully someone can solve it and share!

Does the diesel even have the second battery for the ESS? Or, is it like a normal vehicle with one primary battery?

A dual battery DIY setup is an option. There is room behind the right rear wheel to attach a battery box to the frame. The Cole-Hersee Smart Isolator used by Genesis is available on Amazon for around $100. Warn has a cable kit available for around $200. A stainless steel battery box is about $125. I'm working on a setup to power my winch and lights.

All diesels have two batteries under the hood. One is behind the fender liner, down low. Teraflex had to re-engineer their 3.3 shocks because it is in the way.

Ok, so it still has the setup. Just more reason to do the Genesis setup but in a custom DIY configuration. I'd rather have dual group 34s, 28s, or whatever. Maybe just one large main under the hood, and a 100ah + Lithium in the bed/camper.
