Over the miles, I've learned some companies whose locations are almost always good for fueling my rig - I need the gas pumps out front, and the ability to get 62' of rig in and out.
I've also learned some companies which are to be avoided.
When I plan a driving leg, I also research and plan fuel stops. I know my rig, know how far I can go before I must refuel. I don't push past 200 miles.
I tend to work backwards from my destination. I look for fuel 140-160 miles from the end of the day. If the trip is between 160 and 300 miles, I look for fuel near the mid point of the trip.
The satellite view on Google or Bing Maps is great. I also use GasBuddy to find current rates. Not so much to plan for the stop, but to see which stations in the area have the best prices. I look at the stations on the map view, and make a tentative plan to stop.
Subject to change if I change my route, my destination or weather.
