Which is the best camper van/ Class B RV for winter camping?

[gspark]

Hi, I'm trying to find my first RV and, of course, am overwhelmed by the choices. I'm wondering if anyone can suggest a camper van or Class B RV that can survive Canadian winters. I'd probably just sleep and eat in it, and then use facilities elsewhere.

Any suggestions/recommendations?

Thanks
