U-Haul is the one major chain that publishes a live per-gallon refill price: its propane results pages list each location with its own current price. Each price above was read on that page on Oct 30, 2026 and carries its source link and check date. U-Haul prices are live and change — a verified price here is shown fresh for 30 days, visibly aged after that, and demoted to “last reported” after 90 days (see the methodology). Confirm the current price before you drive.
