We got propane at the Conoco in Columbia Falls that also had a dump with portable water that is located out back, right near the Les Schawb route center. Had very competitive pricing. Heading out of Columbia Falls somewhere between mile market 4-7 you'll see on a curve a small pull off. Would only fit a vehicle to pull off nothing in tow, you'll see a white PVC pipe coming out ofthe hillside. Great fresh spring drinking water. Have fun!

You would need to drive into the town of Columbia Falls to get water and propane. We found a dump site at one of the gas stations and they also had water and propane.

There’s a natural spring a few miles down the road towards town where we filled up water jugs. Propane is available at places in town, I forget the name of the closest town.
