I think Trail Manor has hit a sweet spot with this one. It's light
enough that a small SUV or mini-van can pull it, is more aerodynamic than "stickie" style trailers and many eggs as well, sleeps the two adults and two kids in the average young family, will stay a lot warmer than your average tent camper, and feels big and airy inside because of all that open room at the top half of the camper clam shell. I think it's a great option for families looking for something that has the fuel- and cost- conscious advantages of a tent trailer with the hard-side appeal of a motor home or stickie trailer.
It's downside is the same collapsing design feature that makes the trailer so airy up top also means it can't have a lot of eye-level storage space, can't be used to do discrete overnights in parking lots, side streets or rest stops or be used for a quick sit down lunch or potty stop. I love the back porch, but the rear-entry design means having to climb through the dinette/bed to get to the washroom and kitchen facilities from the loft.
These are probably good trade-offs for occasional family camping trips, but not so attractive for those who do a lot of RVing.
