Rear battery grounding?

[Amart88]

Do both. I have one ground going through floor to frame in rear and front. and one 1/0 run from front to rear. Either one will work. Though, I heard that the frame is actually superior.

Back ground is fine. No need to run one up front unless your going higher power.

I have 2 batteries in the back of my truck and I have a ground that runs back to the front as well as a frame ground which grounds to the frame rail just behind the cab.

Not needed, if you just ground to frame in the rear. (and its legit)

EDIT- i tested with meter, added a third pos run, and first neg run front to rear. Gained nothing.

My vehicle is unibody (The body is/is part of the frame) so grounding in the back worked great for me, everything is one bigass ground!

I am grounded to the left rear wheel well. I know that picture makes it look like a frame, but its just highlighting certain parts of the body really.

This thread illustrates pretty well what I am talking about because you can see him chop off parts of the body in order to make his own frame:
