Hi all I'm new here. I don't own a Pioneer 500, but I'm looking into getting one next summer if it can do all I need it to do. I own a 2013 sportsman 500 and it's mainly for hunting. I've pulled a trailer loaded down and carried a bull elk out with it. I had the head, shoulders, hind quarters, and the kitchen sink on the racks. Way over loaded but still had power to get me down the mountain. Will a pioneer 500 carry my 6'5" 250lbs body, my wife, and a trailer with 400 pounds of elk up and down a mountain road above 10,000ft with no issues. The only reason I am asking is because I live in Colorado and this is the elevation I hunt, and I have heard a lot complaints about lost power at high alt. Thanks.
