One big problem staying anywhere north or south of town off of 95 is the traffic. It can be backed up for a mile or more in both directions on 95 with little movement for hours. if you are coming from Scadden Wash to the east it is a piece of cake to access downtown.
Another option is to stay at the Rice Ranch RV park. It is not much of a park but does offer full hook ups for around $35 and dry camp spots for $7. It is nothing but dirt and gravel but being located in the center of town right on 95 makes walking to the big tent and all of the other "show" attractions, a 3 minute event. We paid for the hookups last year but won't bother this year as we only stay for a couple of nights before heading up towards Parker/Havasu.
