Sorry haven't visited for a while. I am leaving for the Florida Keys tomorrow morning. Will try to post pictures when I get back in two weeks. i didn't install an isolator, I just ran the batteries in parallel. I removed the center console and installed a refrigerator/freezer chest and just wanted a little extra battery capacity since I only drive the van two or three days a week and for road trips. Looking at the Nissan Titan dual battery images the NV is definitely roomier for the battery placement.
