You can put a 911 in a 14-foot trailer but you would have to be a contortionist to do it. Sometimes if you look at minimal requirements you can make it work but are sorry later. Maybe the car will fit but if you change cars, will the new car fit? Will anybody else’s car fit, when you try to sell the trailer? If you have a wide body 911 you will want a 102” wide trailer. In my 20 ft with a wide body car and a front diffuser on the car it’s tight. I have room for a rack in front of the car for storage period. If I did it over I would go with a longer trailer. But when I bought it I though I was going to pull with a ½ ton which would have been at the max capacity of the truck. Bought an older diesel to pull with and quite worrying about ratings. I LIKE the equalizer hitch with an enclosed trailer especially one with antisway, it makes pulling the enclosed much easier.
