Very happy with MudFlap. We travel about 4-5 months a year with our 5th wheel and GMC DuraMax truck. Very nice to pull in and get bulk DEF at truck stops.

Most of the time lately there isn’t enough discount, by the time you pay the fees I really didn’t save enough for the hassle.
Response from Mudflap, Inc.Jun 10, 2025
Hi Raymond, we appreciate you sharing your experience. Mudflap prices and discounts vary depending on retail and the cost each of our stops sets. Fuel prices fluctuate daily, but we aim to deliver the best discounts available to you. Mudflap is free to use with a debit card or bank account, so you can avoid that 1.9% credit card processing fee by switching your payment method. Feel free to reach out at 1-888-885-3835 or [email protected] and we'll be happy to assist!
