I have a Farmtrac 360 DTC with FEL and I have a 20' bumper pull equipment trailer 18' deck 2' dovetail with 2 7k axles, if you ever plan on hauling a bush hog mower or any other 3 pt hitch implements you wont want to go shorter than 20'. I use a 30' gooseneck to haul my big tractor and while I do like how the gooseneck pulls better, I can get the bumper pull in much tighter driveways as it tracks the truck better.
