    Yeah pretty much.

    In my case I have a pair of HID lights, fridge, ham radio, on board air, on board water, lights in the camper and I run a cpap machine at night.

    If I turn everything on at once it draws about 28amps.
    I never do this but it shows how much every thing draws which would kill my starter battery pretty quick.

    Also, the way I have it set up the 2nd battery system isolates the truck’s electrical from everything I’ve added. There’s Toyota’s engineering and manufacturing and there’s me.

    I do have the winch powered off the starter battery. My 2nd battery set up are true deep cycle batteries. They don’t do well with a rapid power drain like a winch does. My starter battery is designed for that.
