Cutting down trees for your satellite signal is absurd. Trimming trees back some so that RV's can safely traverse the roads and fit into the site is another thing altogether. I was at an RV park last weekend that had a small tree at the inside of every right angle turn that was required to get to my site.
While it was navigable, it did require slow moving and carefully hugging the outside of the corner. This weekend the park was fairly empty when we arrived, it would be more interesting during a holiday weekend when the park is camped and there are trucks parked closer to the road.
