any RV parks??

https://www.forestcamping.com/dow/southern/uwhcmp.htm This gives you a full list of which campsites offer RV services in Uwharrie. Arrowhead looks like it offers the most.

Some areas do allow campers. Call the main office and ask for Betty...she can assist you!

Never seen official ones in the forest but I imagine there has to be some around.

Couldn't answer that! I know it is a huge park! They have a web-site!
