We were considering a Travel Lite TT, so did some research on the company. To me, for what we would get and the reputation concerning quality, it was not a fit. As long as one understands what they are buying, the quality and what to expect with longevity and possible issues, it could work.
I am familiar with the unit you are speaking of as I also looked at them online. I do not know of another company making such an product. I was, however, concerned about the aerodynamics, and honestly I don't understand aerodynamics that well. I loved the floor plans, simple and functional and the weights made them attractive too.
I would "google" them.
At one time, that company put our exceptional units, but like others, trying to produce them at an attractive price and still make a profit, quality has slipped.
