Looks great. Your heater box looks proper.
It's easy to catch the trailer plug on a rock, and I doubt the propane connection would fare any better. Do you plan to tuck it somewhere else when you install the rear bumper?
I hadn't seen a Powerlet before. It looks like they can accept heavier cable than a Blue Sea plug, which would help me make a better cable for my fridge. Thanks for the tip.More work on the truck today.....
First up is to install the new Northstar battery under the hood. Here's the original 2012 battery that's being replaced.

The Northstar we purchased is a Group 27, the original is a 27F. The 27 has the posts on the front of the battery instead of the back so the cables will have to be extended to fit. We got a good deal on the 27 so it's worth messing with the cables. We're running a Northstar 31M in the rear for the Aux batt.

While I was setting up the wiring dad was fabricating a stainless base for the ML-ACR.

And wired up. The ML-ACR will auto combine the two batteries when the engine is running and the batts are charging, it will also separate the batteries to keep the trucks battery from getting drained when a load is on the aux battery. You can manually force combine the batteries to jump start the truck from the aux battery as well, a handy feature.

In this shot you can see the Blue Sea low profile fuse on the output of the ACR to protect the 4awg wiring going back to the aux battery, there is a fuse on each battery.

I'm installing a Powerlet port on the heater box to supply power to the ARB refrigerator. The Powerlet outlets are great, they snap in place and won't wiggle loose when going down rough roads like a standard cig plug will, you don't want power to the fridge going out unexpected. I'll be installing the 90 deg fitting on the end of the ARB power cord.

Looking great as always, really enjoy watching your builds. I have a similar battery setup in my Nissan with AT Habitat, how do you plan on securing the battery in the bed?

Blue Sea plugs top out at "heavy duty 18 gauge wire", but Powerlets go to 14ga. I use a fridge slide, so minimizing voltage drop past the outlet is important. I have a longer cord that I eBayed, but it's only 18ga, and it doesn't lock in the socket. I've had it come loose a few times when someone wasn't being careful with their bag, and I'd like to avoid that again.It propably won't support much larger wire athough they are 100% better for a secure connection. You can always make a small pig tale at the plug then jump to larger gauge wire, this will minimize voltage drop and make the small pig tale insignificant when pulling low amperage such as a fridge.
