We'll ignore, for the moment, how Chinese quality-of-manufacture doesn't come up to even the mediocre standards of the American RV industry.
I have had two experiences with tight quarters. First, about ten years ago I found a Ford Transit Connect for sale, used-and-cheap. Had been used as a pilot vehicle for a service that escorted WIDE-LOAD trucks on Interstates. Easy work for such a truck - cruise all day at 65, relatively-few stops.
It had problems, moar related to the Ford nine-speed automatic transmission (my first experience with a modern automatic, POS) but it was sound and a good driver. I planned to camp in it.
First weekend trip showed the problems. With food and gear for a weekend at Yellowstone, I found inside space a bit tight. AND I found that even with door windows cracked, the air got THICK in there after sleeping a few hours. The moisture built up quickly. And the space was claustrophobic - this from someone who did four years in the Navv.
FAIL. That was the start of my short-time trifling with bigger RVs.
Second time was, earlier. My wandering phase. I had just moved to Michigan's Upper Peninsula to take a job (CN railroad, US side) and needed quick lodging. One place with "cabins" for rent (now, life in the UP is like going back 40 years in American culture, or it was, 17 years ago) was looking for off-season long-term tenants. The tiny cabin had recently been refurbished, new paint, new furniture (that's a joke!...no real ROOM for meaningful furniture) and new fixtures.
Looked very nice. I found that just showering, or even washing dishes, turned the place into a sweaty, sticky, condensation-covered mess. Warm fall days you could open the windows. When it's 10 degrees out, and you heat with electricity, you do not.
I lasted a month, finding a MUCH moar expensive off-season summer-home rental.
That toy is designed to sell, not to be used. And that three-wheel design, with all that height...you'll tip it over, inside of 20 miles.
