Nightshade is right, your wheels are why to far back. Idealy your wheels should be in the center of your frame or slightly to the rear of center. You must remember when loading a trailer you have to place heavy items over the wheel axle and lighter items towards the front and rear. Heavy item on the rear ofyour trailer will make it tip up raising your back bike wheel off the ground. Heavy items placed on the front of your trailer will place to much strain on the tow arm.
Move the wheels to the center of your trailer and try a test run, you'll soon see the benifit of doing this.
