I’ve planted hundreds of bare root trees with good success (80+% survival after three years). But they were planted in TN and NC, not AZ, and there’s a significant difference in the growing conditions between the two.
I think your success will be determined by how well the trees are packaged for transport, how well the roots stay moist in transit, and how well you’re able to keep the roots moist until the trees are established. The trees may also benefit from temporary screening to diminish the effect of winds and sun. You’ll want to get them in the ground while it’s still cold enough to keep them dormant for a little bit - probably before the end of February.
My bare root trees haven’t done a whole lot of growing during the first year after planting, then grow a noticeable amount in Year Two, and really take off in Year Three. I think it will take many years (e.g., five to ten years) before your bare root trees will produce an acceptable wind break. When you’re planting bare root trees you’re trading low initial cost for a long time horizon (and in Snowflake, AZ, I think you’ll also spend quite a lot more time tending the trees). Although 1 gallon or 3 gallon trees might initially cost a good deal more, I think they would produce an effective wind break far faster and with less effort on your part.
