@ThundahBeagle Let's be real here. The "Jeep", or "General Purpose" as it is held to have originated, was the combination tractor and pickup truck that the farmer needed. A jeep and a flat/stake bed truck were a great combo.
Modern SxS are as big as the old army jeeps, and serve the same purpose to farmers. The 1/2 ton truck replaces the stake bed.
GP's were designed small, lightweight, and four-wheel drive in order for the military to traverse places where there WEREN'T trails.
"Sport Utility Vehicle" replaced the term "GP/jeep" in the minds of the public around the time they started having four doors, but required differentiation from "station wagons", which were for family road use.
The modern American's "general purposes" means going on paved roads to and from work and the grocery store. This modern "GP/SUV" can be seen in the form of the RAV4, Escape, CR-V, etc. The AWD variants of these are all still plenty capable of more off-road use than the majority will ever see, but for real utility use, a RAV4 isn't needed and a SxS is.
SxS are designed to go where trails do not yet exist, just like the original GP.
So, how does car camping relate to all of this? You can't car camp in a SxS. You can't car camp in an army jeep. You can only car camp when your car is big enough to sleep in. And this size alone limits where your vehicle will take you.
Nevertheless, "car camping" doesn't sound "cool" or "adventurous" to the ignorant who don't know what it is, like "overlanding" does. So it doesn't sell.
Imagine selling an overpriced tarpaulin that hangs from the side of your car and you stab poles into the ground to hold it up, and you advertise it as helpful to car campers. You'd be laughed out of the industry. But "Fold-away awning! Great for overlanding!" sounds cool when you advertise it.
