@Mr_Mnml_Engnr I agree wholeheartedly, these are how I use the terms as well. However, the public's point-missing common (mis-)use has rendered a lot of words meaningless (consider the word "awesome" - once reserved for sights like the Grand Canyon or the Taj Mahal, now reduced to a casual meaning synonymous with "cool" or "nice"), and "wheeling" and "overlanding" are just more of those words...
Anyhow, I also understand how some words are just annoying to hear people use. "Off-roading" or "four-wheeling" are more general terms inclusive of all such activities as rock crawling, mud bogging, winching, driving along the beach, and the like. "Overlanding" means traveling reliant upon your own vehicle and the equipment you take with you, as opposed to "drive" (simply to operate a vehicle) or "travel" (you could use public transportation, or stay in a hotel) or "tour" (visiting attractions in a particular location)...
Words when used correctly have much meaning and nuance. It's obnoxious when people take a good, meaningful word and abuse it and spread its abuse around until nobody knows what it actually means.
@MiamiC70 I think the line between "overlanding" and "car camping" is drawn at the point where car camping is an activity done with the intention of immediately returning home afterward, whereas overlanding requires traveling, whether regularly or as a one-time event. Overlanding does not necessarily involve car camping, as it can be done with a trailer or a ground tent, or other sleeping accommodations.
You can "car camp" in the Wal Mart parking lot (but you shouldn't), but you can't "overland" in the Wal Mart parking lot.
Per the forum's definition, overlanding includes all "vehicle-reliant travel", which includes all forms of personal transportation, with or without the practice of staying overnight anywhere by any means... and it is on the fringe of this loosest definition of "overland" that I participate. I just like to drive.
