My 20 ft ... its a little tight because I carry a lot of stuff.. scooter, generator, but I make it work . I recently added a winch which takes up even more room and its a challenge using it while the scooter is in the trailer but again I make it work. I recommend getting a winch it comes in so handy .. just this past weekend broke a u joint and hurt the driveshaft I sure was I glad had a winch as loading the car afterwards was very easy.
