I'm the same as "ferndaleflyer". We use Gas Buddy in unfamiliar areas. Gas Buddy often offers a photo of the station to see if it's navigable with a big rig.
We're 65' long with the truck in tow and find I can get in and out of most stations. Haven't been stuck in one yet in 11 years. Out west, especially in California, the truck stops are anywhere from .08 - .15 cents more a gallon. That amount isn't going to break the bank, but with my PenFed credit card, an additional 5% discount, I'm looking at .25 cents a gallon and on a 50 gallon fill up, I've got lunch money.
For me, the payment rules, dirty lanes and dealing with truckers is just not worth the effort. We do use Sinclair stations when we see them as they always have nice RV pumps along with one Pilot we use on the Arizona/California border that has RV lanes and great prices.
Over the years, we've identified stations within a 1000 mile radius of our home that we typically use on each trip. So given some time, you'll get comfortable finding stations that will work for you.
