So far Mudflap seems good for long trips where I can plan my fuel stops. I hope they expand and get more stations signed up. I have not quite figured out their deal with Maverick (these are stations in the Rocky Mountain area; very nice, usually have RV islands, dumps, etc). They must be working with stores individually because some are listed, others are not. Not sure why it is not a corporate deal.

I think you can download the app and see if their network will work for you before you sign up and give them your credit card.

Here are a couple screenshots showing available stations:
