Diesel Fuel Discount Program in Type A motorhomes Posted November 1, 2019 · Report reply TSD recently negotiated better discounts at Pilot and Flying J. They're similar to TA/Petro now, depending on location. Just happened within the last week. Love's still gives the best deal on average. If you tie the card to the Love's reward app, you will get the receipt immediately (showing the pump price prior to the discount). You will immediately get the discounted price via the EFS app on your phone. It only works in the trucker lanes in the back of the stations for diesel and DEF. It will NOT work in the auto lanes, therefore not a viable tool for gas coaches.
