    Anyone ever consider using deep cycle marine battery with a regular battery,,both brand new and both 1,000 cca. might be a redneck idea, why does this setup continally work year after year?? Im probly the only odd ball using this setup..

    I do

    the same thing. I have had this setup in 3 different trucks and it works fine. What I do is run a solenoid so that when the truck is off the batteries are seperated. That way one doesnt kill or draw from the other. I leave the factory battery and just buy a marine battery to add.

    Just buy a charging isolator. and hook your plow up to the Deep Cycle.

    Are they wired in true parallel or isolated?

    You're not the only oddball on this site....

    Definitely do protect your steel brake lines, they're a pain to replace and of course you'd hate to find out the hard way that you need to fix them...

    You want redneck dual battery? my first plow truck (rusty but TRUSTY!) 78 chevy, second battery was bungy corded to the main battery, with 2x4s taking up space around them for a snug fit!

    For what it's worth, deep cycle batteries from big box stores/discount stores tend to be just relabeled starting batteries...which I took advantage of when I had a deep cycle battery and my wife's SUV's battery failed. Stuck that deep cycle in, worked great through winter and everything.

    Saw them at autozone called dual purpose. Both deep cycle and normal battery. so you could just use two of them.
