Lat/lon is in the eyes of the reporter, the accuracy of the GPS that took it at the time, and the mood of the person with the GPS at the time the readings were taken. Were they just driving by and too lazy to turn in, or no place to park, is the lat/lon in the center of the roof of the building, or in the parking lot 1000' from which door on which street.
Anyone seriously planning a route and needing to know exactly where truck stops are, should verify locations with an online map service with aerial data. You can use the lat/lon from the program (rt mouse click on the POI and select Info, then copy the Mouse Click Position) and paste it into the websites search. If it's there, it will be obvious, if not look around. When you find it, you can make a fourth POI on the map
I have as yet to see one of these that you really needed to know exactly where they are, as there are signs for them and their exit numbers well before you even get to them, and they are so big you can't possibly miss them.
