Place to park for the night in Flagstaff or Winona AZ?

Thanks for the ideas. I don't want to get too far from Flag. as the temps rise as you drop down into the desert. I mostly just don't want to deal with finding and checking in somewhere as it will be late. Just want to pull over and go back and crash. I found a Conoco station with a lot of space around it and spaces for trucks just north of Flag. so I think I'll give that a try. There is another station in Winona that has a large parking lot next to it.
