We are traveling in a Mercedes Sprinter camper. Great location for a must see visit to the Cave dwellings. Most camping in the valley is free but this is worth the fee for the hot springs and the owners, who are very welcoming. Also the Hot Springs gives you a chance to swap travel and life tips with other travelers. Fee is $10 per person per night and you really need a reservation especially for the weekend. Other campsites in the valley: Upper and Lower Scorpion; Forks etc were mostly empty.
