Dmax 3.0 Adding second battery?

Recommended Posts

Search feature is pretty unusable and did not turn up anything on this.
I am looking to add a second battery inside engine compartment to wire up a 2000w invertor in the bed to.  The idea is that the second battery would be used to handle whatever I want to run off the invertor while driving or parked.
Yes I can just put second battery in the bed of the truck, throw in an isolator and wire to primary but I am looking to see if anyone has done a second battery under the hood, I would prefer not to have a battery in the bed of the truck.  Something a little more factory and a little cleaner if possible.

I'm afraid I pretty much did what you don't want to do and put the battery in the bed with an isolator. But there was no way I could have fit the Renogy 200 A/hr battery under the hood either. I'll definitely throw out there that with the DPF in the engine bay, you're gonna have a bad time if you mount a battery on the passenger side without significant heat shielding. Best thing I can think of for low key mounting would be a non-vented battery under the passenger seat or a compact lithium battery on the driver side of the engine bay. Those body frame rails really cut into the usable space under the hood in these trucks.
