It can heat the cabin for 36 hours, so I'm not too worried about that. Of course just like a gas car, don't show up low

Thanks for the help everyone. I think we should wait until next year for a big winter drive like this. I appreciate everyone's time and input

I think this is the conclusion we're coming to. I need to drive it once in good weather to feel the roads better, then maybe I can do it in a future year during the winter break
