Because our current (and for the foreseeable future) trip(s) are on the same route to/from the same destination, we have become comfortable stopping in the same general locations for gas/food/rest etc. Perhaps due to that, I don't pay attention to gas prices.
In fact, if I knew a certain gas station down the road at one location had a few cents less per gallon, I doubt I would deviate for the relatively low savings. With our current set-up, those stops reflect what distance I know I can safely travel with the gas in the tank.
As previously mentioned, when the new truck arrives, I will compile details from the first run and only use that to determine where the future scheduled stops will be.
Even driving around my local area (the truck is also a daily driver), I never pay attention to gas prices and just buy gas when I need it.
Having said all that, prior to ordering the current and soon to be trucks, I spent a gazillion hours researching every component/option/make/model of the anticipated purchases. Now there is where I "enjoy" meticulous research and compilation of data.
