We are DVC members, but we took a trip to FW previously with a motor home. I had also been there in a motor home with my parents several times as a kid.
The experience at FW is unlike anything else at Disney World. If I still had access to a motor home, I would do it again in a heartbeat. There is such a neat laid-back vibe there. I love renting a golf cart and cruising around the campground.
If you have a chance, I would definitely give it a shot.
