I have a 2003 durango. Its the 4.7. Im looking for a new battery under the hood, what do you recommend? Trying to stay under two hundred. The local auto store has orbital marine deep cycles for 130 on sale or orbitals for 120. Should I stay with the group 27? On the big three I had it ran from the alternator to the fuse box then the battery. This made me kinda nervous. Should I go straight to the battery?
