Thanks so much for the input- everyone - very helpful. Some frank comments that I need to hear so I may avoid problems. I understand that the rfryer' and 2gypsies' contextual differences; each is correct given different geographic and topographic assumptions. I get it.
rfryer correctly interprets my "neat places" comments as smaller, remote campgrounds off the beaten path. I love those places and spend time seeking them out. 2gypsies' campsite pictures are just the type of site I like - trees, etc. I'm happy some treed sites in state/national parks are accessible to a 40, albeit significant compromise at that length must be made generally. I must say at this active point in my life, I'm no fan of commercial style "parking lots". I'd roam the US year round as a full timer; not a snow bird in most likely two week intervals.
Terryallan's comment about Julian Price Memorial Park hits home, because he's talking about very narrow, windy roads with very poor road shoulders. These types of roads are common in the Smoky Mountains in the East. I grew up in Tampa, but am in Greenville SC now and love the Smoky Mountains. As another poster said, a site may be big enough, or not, but that's irrelevant if you can't get safely to the site in the first place, due to low branches and bad roads. This is what I need to hear so I can prepare. It's just geographic context and I need to research destinations much more.
Not decided by any means, but I may scale back to say a 35 FW plus take along a good quality truck tent to access some of the little lakefront or stream sites that I like, which are typically tight and small. Or as crazy as it sounds, I may find a home base out west and buy (or rent) a second (very old and cheeeeeeapo)small travel trailer to explore the neat little hideaways.
Lots the consider........
