I did the same thing. You need to be very careful of tongue weight. I could not move a 20' travel trailer, front wheels came off the ground. Had to put 500# of weight in the FEL and it still was squeezy. Devise a hitch on the FEL, put 400# of suitcase weights on the rear QH. Worked great plus I found pushing rather than pulling is far easier parking it where I want. I even use that setup to move my 5000# capacity dump trailer full of gravel and my 16' lift bed machinery trailer (it weighs at 4,000 empty).
