What @Vtur said. Not Aux Switches, no 750 amp battery.

My Rubicon was the same way, had the tow package with the 240 amp alternator but no aux switches. I had the 650 amp H6 size battery.

Tough to beat the 94R AGM battery from Walmart for $179 with 4 year free replacement. Easy to find a place to replace it if needed. My aux battery has been removed. The original primary battery is still working after 4 years. I do keep a emergency jump start power pack behind the back seat.....

Not sure on the Gladiator because I've never tested it, but many trucks won't have a connection to the battery on the trailer plug full time. On the F450 there is no power there unless the truck is running. Not even with the key on. The truck must be running. We've connected the aux bed mounted tank fuel pump to that circuit to fill the track cars with fuel at the track.

Apparently it’s live unless I’m missing something. See post #10.

Just checked. It's live. Didn't even have the fob with me.

Here is a post I made about using the trailer plug as access for charging the batteries.
