Prices can range from free on national forest land with zero hookups to nearly $100 per nite for a "country club" style park with all the amenities. There are several groups one can join to get price breaks at some RV parks. Since I am airborne now, I can't access my files while typing on the iPad.
One is the Good Sam Club (Camping World).
