    Assuming you have the passenger side battery tray now.
    Look for a 6.2 diesel model as they have one on both sides.
    At a minimum you can use the driver side battery tray.

    I’m just adding an extra battery for the total amperage ability-no need in my case to run a seperator-I have stereo plans tho hee hee. I am using 1/0 gauge cable and 1” high heat looming, HD battery crimp connectors. I’m basically replicating the factory dual battery (TP2) RPO option.

    I am going to run a boat trailer winch and a portable 12v air compressor for airing up tires.

    I run alot on a single. Winch, inverter, extra lights. All about alternator. But a dual would probably serve you well.
