You will not regret getting at least an 18' . I started with a 16' and went to a 20'. Be sure to get a solid floor and not open center. I have my trailer set up with winch and in front i load a golf cart from side with about 21/2 ft between it and the car. I am now mounting a truck tool box on tounge and as Mike says you will have to space it up to be even with the deck..As far as towing i could not tell any diff in the 16' to the 20'. I bet Mike has just what you need.
