No it's not necessary, but I'm also not gonna delete it either... eventually it will be useful for audio and some headrest TVs for the kiddos...

More power to ya..
If I could easily add a second battery to my rig, I would. Especially with the addition of audio and video aftermarket doo dads.
You can all you need is a battery tray, battery holder, and a couple cables for a parallel install.
Thanks. I know the parts needed because I have done the add the battery thing before on another rig plus my old 73 Blazer that I built as a rock crawl 4x4 with one ton axles and all kinds of goodies, had a double battery set up. I was just wondering about the room. Anyone have pics for this on a NBS rig. Mine is a 2002.
Just went and popped the hood to look. I am assuming the go to spot is passenger side at the firewall? It's either that or a relocation of the air filter box. I guess the extra battery tray is a direct bolt in at the passenger firewall?
If I recall, from before, all I did was bolt in the tray and the new battery with the holder and had positive cable that ran from main battery to the positive on the new batttery and ran my ground to a spot on the block.

Here's pics of my dual battery setup on my 06. The setup is very similar on my 09 Tahoe. Shockingly I don't have any pictures of my L9H.

Why is there two cables off of the positive? I thought all I would need is a long enough cable with two female connections from my main battery positive to the 2nd battery positive and a ground off of the 2nd battery to the block.

I have one to the positive and the other one is going to the alternator. The 06 has RVC and I did it this way to make sure that other battery gets charged.
