I really like keeping 6 volt. I get lots of thumbs up and positive comments at car shows because I kept it on the original side. When I first got the truck a year ago I added ground straps and upped the ground “wire” to a 2/0. I threw the first 6volt battery I could find in it and the starting has never been a problem since. I’m not sure the battery is a “best” for it and will look for that when this one gives out.
