*to clarify the snow 10+ inches usually would be on the flats before getting to the mountain pass. If there was 10" unplowed on the pass they'd close the road until it was cleared.
Thanks for all the advice. I am hoping that we can get away with one awd/4wd and the other be one of the cars we currently have with snow tires and keeping chains in the trunk, with down the road changing out out not so efficient car for something more efficient.
@MsPeacock-i have spoken with some people who live there and the answers vary depending, but most of them said awd/4wd is practically a requirement to work on the other side of the mountain, which is what I'd have to do. One person did say on bad days you can make it with a good v6 and chains, but I have yet to see a v6 that gets good gas mileage.
@Dmy0013-Those who drive the pass have at least snow tires, if not studded tires & I am a nurse so no staying home for me unless the roads are closed.
So that's the snow/tire part of that, how about any vehicles with good mileage and the ability to get up and go up a steep graded mountain pass?
