National Truck Stop Directory - don't drive without it! Works even when your 3G/4G network fails. 1,000,000 copies of The Trucker's Friend have been sold. Nearly 400 pages of maps and truck stop services help professional drivers stay productive on the road. Listings are alphabetical by city as well as in exit order by interstate. The RVerâs Friend - The same quality maps and truck stop data as in The Trucker's Friend. RVers can find truck stops that sell diesel, gasoline or propane. The directory also tells which truck stops let RVers park overnight or have dump stations. The Fuel Finder - A pocket companion to The Trucker's Friend and The RVer's Friend. Fuel Finder has no maps and lists only the essential information (24/7, parking, food, showers, and repairs) about each location. Published by TR Information Publishers. Contact us today!
