It was a five-day stretch for us from Grants, NM to Silver City. There are no stores (there is one restaurant - at Pie Town), no gas stations, no nothing for 5 days and lots of miles. I'd never had to provision for that many days before, but we went to Walmart in Grants and stocked up. Then we had to figure out where to put it all, wonder if we could carry it, and worry about whether it would be enough. We got 2 large boxes of oatmeal for breakfast, 3 bottles of peanut butter, 2 jars of jelly, lots of trail mix, and four of our normal dinners (rice or pasta or ramen, something good to go on it, and some fresh onion and green peppers). We made it just fine, with a little bit of food left over, but certainly learned that we can provision for 5 days.
