"We wanted to leave some trees for shade but I hadn’t considered trees interfering with satellite and WiFi signals. We’ll still try to leave some but will take that into consideration."
PACKBACKER, THOROUGHLY CHECK WIFI SYSTEMS BEFORE YOU START CUTTING TREES.
I don't believe any park could have more mature trees than mine. We "grew" our WIFI system over a period of about 8 years, and mainly due to evolution of the available WIFI equipment, we have a system that covers our 13-acre park extremely well. In process of installing AT&T fiber-optic lines to further improve the capacity and speed.
You may need to place satellite dishes a little further from RV sites than you would like, but that's just a matter of running longer coax cables underground.
Even with very dense, mature trees you can find open spaces for satellite signal.
Trees and water in an RV park, especially here in Texas, is invaluable to it's success, IMHO.
Good Luck
