I bought one of these Runaway trailers. I worked my butt off trying to get it where it would be comfortable. And they are not comfortable. Like someone else said just a box on wheels. Crawling around inside on your hands and knees is no fun. And banging you head every time going in and out of the tiny door is dangerous.
I took it on a 1 month trip camping. It was the most uncomfortable thing I have ever been in. There is no vent fan and there is 8" of dead air space in the ceiling above the windows. Even with the ac on it gets very humid in it. Everyday I had to remove the tri fold foam mattress and set it up to dry out. These things are very small and uncomfortable. They are also constructed very cheaply. There are no side supports, I noticed that they shift like a cracker box. In other words they are not squared after traveling with them.
Also, the AC unit is very loud because it is mounted on the walls and the sound is transferred throughout the box. And yes it is just a box on wheels. I sold the thing as soon as I got home. And I lost my butt on it.
My 2014 Ford Escape is more comfortable to sleep in. When I am traveling I go to the campgrounds or where ever and fold the seats down, pump up my air mattress with the electric air pump plugged into the rear powerport and sleep better than in that crappy little Runaway utility trailer. They are sold under the classification of a utility trailer when you buy it. They are not campers, they are utility trailers with an AC stuck in the wall.
And very over priced.
