Best electric van?

So I want to half move out from my parents. I would also love for my first very own car/appartement on my journey to be an electric vehicle. What would be the best either used or new? Helpful if the price is also written but not necessary.

In the recommendation, what type of work would I need to do to get it to withstand the Canadian cold, going sometime under -40°C ? The base specs would be to fit a bed and a small counter to maybe cook pasta with a little induction oven put on top. I love the van lifestyle and have been lurking in this sub for a while. I also love the idea of a minihouse so even then, I just need suggestions to help me choose between an electric van, a gas van and an RV. Any answers help :)
