I'm headed to Moab, Ut leaving NC on March 20. I'm trying to plan out every detail of the trip possible before hitting the road. From what I can find, it seems the cheapest fuel along 40,actually cheapest I've seen in the country, is around Oklahoma City. That will be almost exactly halfway for me. I'll have ~140 gallons with me when I leave NC, more than enough to make it to OK before stopping. I figured since some of yall are from the midwest, you might have some more insight.
