I full-timed in a truck camper (one person) for a couple of years, all over USA and Canada. Had no 'size' problems. This was a while ago (eight years)... Did one year in a van, with a tent, earlier, college years.
๐ Fun.
Now, Genie and I spend at least six months out of the year on the road, and many shorter trips. Still in a truck camper - we have no issues with space. But we rise early,spend our days driving or walking or 4x4 trails, and go to sleep early. No TV, no e-games, but we read a bit. And we spend time on the laptops - we write and photograph our travels. Our days are pretty full.
We'd feel a 24' TT or 5'er would be like a castle - except when we moved it. But we also stay short trips in each CG too ... a few days, at most a week. It depend on your lifestyle and what you expect on the road and from the places you stay. We love NP, SP, COE, and never stay on private CG. We also camp at military CG's when they fit our route.
Remember, the entire outdoors is your back yard. Enjoy it - we do
