My first trailer was a Sloan 20'. My buddies had the 18'. The 20' was better because it gave me enough room to carry an extra set of tires in front of the car. Since that time, I've owned enclosed trailers of 20', 26', 40', and 28'. My favorite is the one I have currently, which is a 28' made by TPD. The tongue adds an extra 4' to make its overall length 32'. This is the perfect length for a single-car enclosed Viper trailer.
