The Compact Jr is a very light weight travel trailer that was manufactured *around* 1971 through 1975 by a company called Hunter Structures, Inc.
There are plenty of reasons that a trailer like this one is beneficial...
This can be a great choice of trailer to restore because once finished it fits in your garage and can last you many more years.
Here is a picture gallery of someone's 1973 model. As you can see it is easily pulled by a car.
