Welcome to the forum from the "other side" .
I'm not sure if the Premier comes with the infamous "Arctic/Polar/Glacier" Package, but if it does and the salesman tries to tell you that it will withstand sub-freezing temperatures for long periods of time, just say...."Sure".
These packages and the designation sticker on the side really mean that the RV is good for 3 seasons where you live.
Seeing that you are from Alberta, you know all about cold so I will say no more.
