I had many plan on building one. Liked the idea of it being a bit more solid/waterproof than a tent while still being small and able to be pulled by a smaller truck (s10,ranger). Howerev my wife decided it would feel too clostraphobic so my plans have changed to a full size truck and a truck camper or regular trailer. Even though she is fine in the small space of a tent with the soft sides, the though of the small space combined with solid structure of a teardrop just seemed to scare her away. If it were just me I'd be fine sleeping in the back of an SUV so its soemthing to think about if our bugging out with family.
