One last consideration should you choose the LiFePO4 route: these batteries can't be recharged below 32 degrees F if I recall correctly.

Many in our "circle" have gone from AGM to LiFePO4 and discussions abound about this aspect of them. So, if you want to be out for several nights and it's cold.....
