Deadhorse Ranch SP (AZ) site recommendations?

We stay there each winter for a week or more... Except this year as DW had to get a new knee. We like the upper areas, but have never had to have a reservation. All RV spots have water and electric with a dump at the entrance to the park. We don't care for the lower areas as they have a lot of overhanging trees that WILL scratch the side of a unit. Try the trout fishing in the river or the ponds. All plants, but a lot of fun. While at DHR, go up to Jerome and have lunch or dinner at the Haunted Hamburger. Hamburgers and desserts to die for.
