It's cute, I think I remember hearing about this style a few years back. There is a decent sized teardrop trailer market among the classic car folks.... so some might want one to go with their car.
It is sad that the manuf hasn't considered putting in some real spec's like interior headroom. When I built my 2 teardrop trailer sized gypsy vardo's I think I had the center height around 54", just tall enough to sit on a milk crate in side(was thinking of adding a small porta potty)
Yes I had fun towing it around...but honestly when my boat got totaled from Hurricane Sandy I bought my ParkLiner
because I wanted to be able to stand up inside...and a fridge
and shower and all that made the camping experience a lot more fun. But everyone's needs are different.
