Great stuff guys. Love posts like this.
I did a second battery upgrade to my 2000 Silverado, did not use the isolator, batteries are identical, but I am not loading the batteries "yet" to where it is a concern.
I don't have that little box in my truck I just did the the big 3 upgrade can't I just run a fuse holder from you to other instead
Does anyone have the photos to this thread? I would like to add a 2nd battery to my 99 suburban
