Unless there is something I don't know about, most trees take 30 - 50 years to mature. Pretty hard to anticipate what the needs of RVs will be in 2068.
Design of parks is almost entirely dependent on the topography and unique features of the site. Flat, level sites with straight wide roads might be easy to construct in a Kansas cornfield. Not as easy to carve those features out of the side of a mountain. Placing utilities in the ideal spot isn't always possible. Sometimes that would require removing a 200 year old tree or blasting thru 50 feet of granite.
Personally, I don't want exact uniformity in much of anything other than McDonalds.
