I like it a lot makes things simple an quick. Except for trying to get fuel at the maverick. They want specific amounts for fuel. It helps out a bunch with repairs an what not outside of the box. Nice!!

You guys overcharged me took too much of my money. Not right
Response from Mudflap, Inc.Jul 20, 2026
Hi Richard, we're sorry for the frustration. What you saw was most likely a temporary authorization hold, not an extra charge. We place a hold on credit and debit cards to make sure funds are available before fueling, and any unused amount is released once the transaction is complete or the fuel code is canceled. Depending on your bank, it can take a few business days for that update to show on your account. That said, our support team will be reaching out to you soon to take a closer look at your specific transaction and make sure everything is correct. If you'd like to connect with us sooner, feel free to give us a call anytime at 1-888-885-3835. We're happy to help.
