I would suggest you to sit back, don't touch any equipment, read much more of the forums, and ask educated questions related to box design and a systems electrical.
Krakin I've tried reading up and posting threads, asking questions and I always get different answers. Always. I asked what size alternator I should get, some people said 250 with 3 batteries, some said 270 with a couple batteries, a lot said a 370 with 4 batteries cause they like overkill. What's your OPINION on what I need? I know that there are always debates, thats why i want an opinion. You know what I'll be running.
