This guide book contains the location of more than 400 fuel stops along US Interstate highways. Maximum distance between fuel stop is 300 miles. Access to fuel pumps is based on testing with our 39' gasoline RV pulling a tow vehicle. Fuel stops are listed by Interstate Highway and by State. A fuel stop is identified by Interstate Exit number, mileage and fuel station brand. Direction of travel when exiting the Interstate and travel direction to the fuel stop are identified. All fuel stops have gasoline available and the guide shows if the station has diesel or propane. Our favorite fuel stops are identified and information about overnight parking, food service and campgrounds is provided. In order to meet the criteria of a fuel stop every 300 miles some stations with higher prices or access delays during rush hours have been included. These useable but less friendly stops are noted along with stops where your access has to be a specific pump. Stations were selected based on hours of operation, access, fuel price, and additional services available. Make your RVing experience more enjoyable with our guide and tell a fellow RVer about it.
