Flying from NC to Pacific NW for RV trip - Need advise

You could pick up your RV in Boise ID, you could make a counter clockwise loop back to Boise. The rental would be cheaper and I think you could see everything on your list. The question is whether 2.5 weeks is enough time. You could spend several days in Yellowstone alone. We saw the Tetons in one day and Glacier in 2 days. Cruise America rents in Boise.
