My 99 Country coach as mounting space for up to 8 8D batteries. Currently there are 6 installed and I'm contemplating only putting 4 in when I change them back to AGMs. At over $550 a battery I don't want to needlessly buy more battery capacity than necessary. My last coach was 2008 Beaver Contessa 42. It only had the equivalent of 1 8D and one 2500W inverter. I know my DC loads are a bit more, but I can't imagine they are that much more. We don't do much dry camping, so I can imagine being on battery power for more than over night. During the day we can always recharge them with the generator.

So for all of you that have far more experience with a bus conversion than I, is 4 8D batteries enough?

Thanks,

Gil
