Using the globe/display capabilities of Marble and publicly available data, you can see where weigh stations, truck stops, and rest areas are around the country in an easy to use, intuitive manner.
TSL is not designed to highlight every single possible diesel refueling location in the USA. TSL is specifically designed with the over the road truck driver in mind, with the hopes that it will make life easier to plan repeated trips across the 48.
