Okay, I'm 52, hardly the "younger" generation, but I have 11-year old twins (twelve next month), so I will stand in momentarily for the 30-somethings.
My grand-parents had a tent-top camper, with room for a family of 5 if one kid slept on the floor. My grandfather built it in the 40s. When my parents married and spent their first summer together camping in a canvas umbrella tent (my dad was doing field research for his PhD in geology--in the Colorado Rockies, of course!) with a new-born baby, Grandpa gave them the trailer. We camped in it every summer until I was 11, when the frame of the trailer got broken on a really bad "road" (cow trail), my parents divorced, my dad married a non-camper, and life as I had known it ended. (It's okay, my step-mom and I are really good friends now, but she never did take to camping. She and Dad took a number of separate vacations so she could cruise and he could camp.)
Anyway, one of my first purchases in my early 20s was a tent so I could go camping again. An old canvas umbrella tent, in fact, for rather glamorous remote car camping with a bunch of friends who had similar tents and styles. I soon decided that I didn't like sleeping on the "floor" any more, so I bought a cot. And a chair. And a table. A kitchen set up. I was a single woman with a big station wagon, and later a cross-over SUV, just for my camping stuff. No room for anyone else, just my stuff! And that worked in my 20s and 30s.
At 40 I had twins, and suddenly I was filling the car just with their stuff. No room for my glamping stuff. We went on one camping trip with my big old canvas tent, my cot, their little air mattresses and sleeping bags, a much reduced kitchen, and a fence (transported on top of the car) to go around the front of the tent to keep them in control. (They still got away from me for a while!

Fortunately my "village" was there to help me round them up.) It was exhausting!!!
I bought a used pop-up trailer. My Subaru could barely pull it, its canvas was rotting, and so was its plywood floor. We used it for 2 years. But setting it up and taking it down was, you got it, exhausting!
We have toned it down since then. I bought a nylon tent and reduced our tent weight by about 60 lbs. We are wall-to-wall air mattresses and cot (I'm
really too old to sleep on the ground
now), but happy. Ricky got into scouting for 4 years, so we have kept camping, but we have done most of our camping in sites with picnic tables. I don't bring my kitchen set up any more, other than a Coleman stove, gear box, and small ice chest. We buy our food supplies in the town nearest to our camp site.
It's
still exhausting!
I was thinking of building a tent trailer, like my grandfather did, when I found this site. But I liked the idea of a teardrop or a small camp trailer (more likely the latter, with 2 kids). So Penguino I was born. It really only got used for one full camping trip, and blew over on the way to the second. However, it got USED a LOT! Dear son claimed it as his "man cave" ("BOY CAVE!" dear daughter and I reminded him many times!). It became his club house, with the boy twins down the street, as it sat in our driveway, in various stages of completion. Now he is getting rather impatient that the Penguino II is not completed yet, because he
needs his boy-cave space!
Anyway, I took July off, but got back to work on P II today. Ricky, at a guess, will build his own foamy man-cave camper as soon as he has his own car in 5 or 6 years. (Patsy wants my car eventually, so she will probably want my trailer, too. Then I will start working on my "retirement" teardrop rather than a family trailer.)
We're having fun, and we fully intend to keep on camping! In COMFORT!
