    Okay this is for all you guys who upgraded you trucks to a dual battery setup. I am looking for the part # for the tray and the batter hold down. I did a search, but could not find anything that listed the part numbers.

    Thanks

    Lou

    Call up your local GMC/Chevy parts dept. They should be able to give them to you. WAIT!! I think I have my receipt in the draw next to me..............

    The Tray PN is: 15705102


    I didn't use the factory hold down because for some reason it was on back order and I needed the dual setup that day.

    Bad and Sonjaab,

    Thanks for the replies. I really would like to have the factory isolation setup... When I get the tray I will have to talk to the part guys about the remaining parts...

    Ahhh. After much debate i decided to not isolate my batteries. I did not know that there was a factory option to do so!

    Either way you do it, go with GM or Painless parts. This way you know your getting a quality component.
    Good luck.

    FROZEN...............From the posts over at the GM truck forums
    that Painless kit is 50 bucks. Not sure how much extra the
    isolation switch deal costs. But I guess you won't need it?????

    The Painless site is a BIG PIA to navigate tho.
    You could try to call them direct for their kit and full info.
    Its gotta be cheaper than buying the parts from GM anyhoo.

    From what I understand the Factory option only isolates the batteries when the ignition is off to prevent one battery from draining the other I guess... Sort of understandable
