Hey all, we ended up getting water at the KOA in Holbrook…$8.00 to use their dump station/water fill.

We got water at the Maverick station in Holbrook. I don't think there's anything in the immediate area of the free campsites there at the entrance.

The Maverick fuel in Holbrook of I - 40 is the closest.

I think there is at the campground, but we didn't stay there so I can't say reliably. We stayed in an old parking lot east across the park entrance from the gift shop. There is no water where we stayed.

They have power and water if you get there before 4 PM. The shop closes early and all is locked up.
