Ski-about advice

Hello all...

I am contemplating a 10 day ski-about this winter, rather than the
usual resort trip. My thought was to start in Calgary and hit Fernie,
Kimberly, Kicking Horse, Banff each for a few days. I am from Ontario
though, and I'm sure there are some smaller places that I should be
skiing. Does anyone have any suggestions for "second tier" mountains
that shouldn't be missed?

Also, I am considering renting a winterized camper and I'd be
interested in your thoughts about sites to park the thing!

Thanks from the flats of Ontario!
