The few times I've been to Nevada in November, December, and January I never even found the need to get out of the truck except to shoot. One day while driving the back roads outside of Elko we shot at 10 coyotes in 2 hours. We tried calling them in that day too but didn't have any luck. We decided it was better to sit in a warm truck and just hop out to shoot at one when we saw them. hahahah We ALWAYS see more dogs in the first 3 hours of daylight than any other time of the day, but when it's cold out they seem to stay on the move all day and you can catch them at any time.
I know it's not the best advice but it's how we hunted them there.
