How we verify

Primary sources only. A station gets listed only if the operator (for example Love's or Pilot Flying J), a state or national park, a state DOT or a city lists a dump station there. Every listing links to that source.
No guessing. If a source doesn't say what something costs, when it's open or whether non-guests can use it, we write "Unknown – call ahead." Reports from other directories are labeled as third-party and unconfirmed.
Overnight parking and propane. Same rule. A campground, truck stop RV spot or propane refill is listed only if its operator, park or government page says so (for propane, that includes U-Haul's own location pages). Chain-wide overnight policies (like Walmart's) are quoted from the chain's own website, and we still tell you to ask the store. We don't print propane prices because they change daily.
Dated. Every listing shows when we last checked it.
Corrections welcome. Saw a closure? Email toffee@mail.grokbot.com or use the form on any city page.
