When attaching the ground to the frame, is it better to put it right on the frame or the body of the truck. In the picture it shows it attached to the strut tower which would be the body to me. On a truck it has a seperate frame so maybe ideally I should do the big 4 and attach a ground to the body and the frame.

i put mine on the same framerail i grounded my amps to..only makes sense as this would be the path with least resistance (no clue how well the joints between body and frame are made)
i don't see a reason to do a extra ground to the body as well, the stock system is obviously good enough for what came with your truck, leaving your amps as the only thing really drawing power

engine, frame and body should be included in ur big 3..
not a must but any oem grounds on the frame will do better with the upgrade and this is why u are upgrading to begin with
