Suggested routes from Pensicola beach to Las Vegas

I would take I-10 to I-49 in Louisiana north to I-20 at Shreveport. To bypass Dallas, at Lindale TX, take US69 north to US380 west. In Wichita Falls TX take US287 north to I-40. I-40 west to US93 at Kingman AZ. Take US93 into Las Vegas. Should be plenty of fuel stops along this route.
For fuel stops, we find Pilot-Flying J or Loves truck stops. Pilot Flying website has a trip planner feature that will show all their truck stops along your route.
Once you get your route we can help with places to stay.
