I recently discovered a fuel discount program that is legit. TSD Logistics offers their normal OTR Trucker discounts to the RVer's. (If you run diesel, you are eligible.) (You have to use the truck islands so your truck has to allow the large nozzle.) I got my EFS card in the mail last week. It's through TSD Logistics and is good at Loves, TA/Petro, Pilot, Flying J, Sapp Brothers, and Road Ranger. TSD keeps 10% of the savings for the service. I drove to Georgia Saturday and used it for the first time. Listed price was $2.69, I paid 2.19. This was at a TA in Spartanburg, SC. I wished I had a bigger tank. Diesel is $3+ where I live. It's a "No Brainer" if you travel or have a listed truck stop near your home. I read this morning that they have over 11.7K RV cards in use as of today. Facebook page, "TSD RV Fuel Program" People list similar results all over the country. There is also a phone app called "EFS Card" that works with the program. It will show you where the best discounts are based on your location and route. Another thing the Card offers is a $200 cash advance. If you only have one diesel fuel vehicle, let the card stay in that vehicle. If you were to lose or forget your wallet, you can get fuel and some cash to get you home. If anyone here is considering getting the card, send me a PM before you do. They offer a referral discount.
