There is little competition in the Billings area and  they increased the rent and eliminated weekly rates.  This is the most expensive campground we had in our year of full time RVing.  There are advantages in that it is very convient if you have business in Billings and there is plently of room for big rigs.  However, they put us in a site that was narrow and had a nearby tree so we could not put our awning out.  The park is pretty with lots of tall trees and the hike to the river is very nice.  But the price is just too high.
