That’s why I always carry my Honda generator to enable me to go on my travels all year round.2 x 100 amp would be better as the days are rapidly shortening and battery use will rise ,as solar out put falls to almost nothing in winter months . I also take a spare stand alone battery just for tv . I would only camp until heating fails.

As a responsible adult you live how you want livewhat do you mean by cross-wired? please
