I would like begin my first post with a big thank you to all who have shared their knowledge and experience on this forum. Without that, I probably wouldn't be entering the solar jungle! I hope yo...

Pianotuna - as we have posted ad nauseum, we went to LFP two years ago but we do not have the extreme cold that you have. NASA uses a type of lithium battery that will charge at -30 C and Manzanita Micro has told us that the CALB cells they use will safely charge at far below 0 C which is the limit for certain LFP formulae. We left rig for three months at son's place in mountains of NM and it did go down to -10 to -15 F (- 23 to -26 C) and left battery suite connected. There is no noticeable decrease in capacity. We do have enough battery capacity that we could put electric heaters and insulation around the batteries and keep them above 0 C. We have replaced all bulbs with LEDs except for the main storage area of 5th wheel (Basement as my wife calls it). There are four x 40 W incandescent lamps in the basement. We have left two of them running on battery on cold nights to keep pipes from freezing and that only gave us a -1kW-hr deficit. Probably only require a one 40 W incandescent plus insulation to keep the forward bay (battery suite) above freezing. However, we choose to go south when it gets cold.
