Anything new in batteries for solar
I have four 31 size lead acid batteries. They are heavy and you only get to used half their capacity. Is anything come up recently that could be a reasonable replacement--probably lithium?

So get a battery warmer.
That is the solution.
As these batts are usually installed in the warmed part of an RV anyway, it shouldn't be much of an issue when boondocking and propane heat is available.
It's when travelling in sub-zero weather that had me wondering. N8GS's solution sounds right: insulated battery box with 12V heater run off the truck's alternator or something similar.
And when putting the trailer in cold storage with no heat, just isolate the batts from any charging source, or loads.
It does make things more complicated ...
I have a schematic (ladder logic) of the wiring for my batteries, Converter, battery monitor, inverter, battery heater and the dual coil latching relay that shuts everything off remotely.
I have pasted a copy of it to the bulkhead in the battery bay in case I ever need to troubleshoot something.
