I don't know much about how they get this rating. I was just surfing through Polaris website and noticed that the Ace has a Hitch Towing Rating of 1,500 lbs. This is identical (if I didn't read the specs wrong) to the Sportsman XP 850 HO EPS. That doesn't seem right to me since the 850 has a bigger engine. Can someone explain to me how they get this rating and how they are the same? This may be a stupid question, but might save me a headache down the road. Thanks!
