I also have the same model. I feel this trailer should have been a tri axle. That said upgrade those tires, especially if your hauling a rzr in back. I have put 4 dirt bikes and gear in the back , but no water in the main tank and had no issues. I am pulling with a dually though. I used a 2500 for my first year.
