Upgrading to Lithium with Solar...

Itenerant1, For most rv’ers,I can see the benefits of a system similar to what you described. However, we live in what some would consider extreme.....and camp likewise. For my particular situation, my concerns would be keeping the system warm enough, when boondocking in zero or subzero temperatures , with minimal generator use. I realize that they generate heat as a byproduct of consumption/use. With that in mind....do you think that in an enclosed/insulated enclosure of minimal cubic feet, with the batteries being used ( running RV forced air ), do you think that they would produce enough exothermic heat to maintain adequate temperatures inside the enclosure? I realize under these extreme conditions that some generator use is necessary, but would like to minimize.

Thanks for your patience!
