    My 2011 already has the second battery tray in place. I was thinking about adding a second battery to run electrical stuff. Has anyone done this yet?

    There is a thread I saw last week with pictures of someone doing this in their suburban. I will look around and add the link if I can find it again.

    Found it!

    I have done it both way with a batter isolator and without one. I have two in my s10 without a isolator, ran off the front battery and it works fine. I have it fuse at both ends.
