I agree that there is a difference of style:
Camping - going to a campground/boondock with the express intent to "experience the outdoors". Hiking, boating, etc. are the activities du jour. Creature comforts are varied, but the main purpose is to just be out in the outdoors and away from "civilization". The place where you park your RV will reflect that outdoors as much as possible.
RVing - going to see the sights, visit people or things, etc. It may be to spend a winter near the grandkids, attend a rally, visit famous battlegrounds, etc. The place where you park your RV is chosen for convenience, creature comforts, etc. It does not have to reflect your particular interests.
Neither is good or bad. Many young folk RV. Many older folk Camp. There is a lot of middle ground - especially at national and state parks that are trying to cater to both sides of the coin. These usually have group activities, hookups, etc. so that folks who aren't interested in a 15 mile hike still want to visit.
I think the hardest thing is trying to figure out what type of place a poster is looking for, or has visited, when they all use "camp" and "campground" regardless of what they're doing. I do like the distinction between "RV park" and "campground" to denote the different focuses of the place.
