Explore the Hardin Area

Fresh water fills are available at several locations around town, including the city park on 4th Avenue West and some of the RV parks that offer dump services. Don't assume every dump station has potable water available, so top off your fresh tank when you find a reliable source.

Propane refills can be handled at several spots including the Cenex station and Tractor Supply Company, both easily accessible with an RV. Fuel up at the truck stops near the interstate rather than trying to navigate smaller gas stations downtown with a big rig.

The dump stations at private RV parks generally have better rinse hoses and cleaner facilities compared to basic sani-dumps at gas stations. It's worth paying a few extra dollars for the improved experience, especially if you're dealing with a particularly messy tank situation.

Stock up on supplies at the Family Dollar or Dollar General if you need gloves, hose attachments, or cleaning supplies before hitting the dump station. The local hardware store also carries RV-specific items, though selection is limited compared to larger towns. Keep cash handy since some of the smaller facilities prefer cash payments over cards.
