Not sure if it's necessary but almost everyone does. One fuse right after the front batt and one right before the back one. So 2

Well I have a 300 amp fuse on the line running to the back just to be safe. The only reason I was asking is because I would gain 0.3 volts at idle if I didn't have a fuse on the line. Then for the run running from the rear battery to the 1500 I just used a 200 amp.
