First off you have to go through the Rambo gate for commercial vehicles. It is closed on weekends and at 6:30 in the evening. Not sure what you do in off hours. Call SPs I guess. There were three semi trucks ahead of us so we to wait on them to get cleared. They brought their K9 dog into our RV to check it out. This was the worst experience we have ever had when entering a base. The camp was full but we parked in the overflow. There was one ahead of us waiting for a hookup site. We got one the next day. If it were not for the hot temps and needing to have electric for the AC I would have stayed at the overflow. It was just parking in a field but we had a nice tree and it wasn’t crowded. There are trees in about half of the camp. Sites are close together. The camp needs some TLC. Laundry was inexpensive, 50 cents. Walmart is about 5 minutes away. Also some restaurants and a theater. It is a little ways out from Spokane. Campers can stay 30 days which probably keeps it full up.
