How to build a LiFePo4 battery bank.
A lot of people dont have any idea how easy it is to build a DIY LiFePo4 12V battery so I'll post a deicent video of how to do it so people can decide for themselves if it is in there capability. ...

Freezing temperatures with lfp is certainly something to think about and have some sort of plan "but" from my experience over the past years unless you will be in below freezing temps both during the day and night your cells should stay above freezing without issue.
I've posted before that all my cells (20) have a temp readings, I can see compartment temp and know what outside ambient temp is, even when I was in a strech of nighttime temps of 13-17f, daytime temps 37-45f none of the cells ever dropped below 40f by morning and during the day would warm up to low 50f. Even having a small load 7-9a on the pack all the time will not warm the pack.
I would let the batteries charge at what ever the solar would produce and being winter that's not awhole bunch till 9-10 when the sun would get some height and be able to hit the front panels along with the panels down the door side of the 5th wheel.
If needed and throwing a hold over charge of 100ah (.2c charge rate) from the inverter/ charger & generator with the cell temps at 45-50f seems not to effect the batteries performance yet after 1,800 partial cycles.
