You're coming up really tight on space in that Jeep anyway and for the cost of dual alt or throwing away your existing alternator to get one that claims 370 (hot I'd believe it when I see it) AND a couple more batteries and you're almost in for the cost of a LiFePo.I have a 6 phase hairpin 270 in there now.
I'm looking to add more power at some point and I'm pretty convinced that's the way I'm going.
