And it's Friday the 13th... The T-1275, due to it's shape and proportions, is a bugger to get fully charged. It takes a lot of time to get it top charged. It's shaped more like a car jar.
If you are serious and want the least amount of effort to get as near as possible to fully charged while camping, I would suggest a pair of Trojan T105 GC2 6V batteries, and wire them in series for 12V. They are much less effort to bulk charge, absorption charge and top charge, as well as equalize. They are the proper, most efficient shape and relationship of lead plates to battery acid, hands down.
Just saying, as I have some hands on experience with a couple of T-1275's. Great batteries, powerful batteries, but it takes a long time to get them fully charged, or equalized, not the best attribute when camping with them with running a generator and solar panels. And if you are hooked up to a pedestal, you really don't need GC-2's or a T-1275.
