My Rhino performed flawlessly on the moose hunting trip...
Compared to my Yamaha Grizzly 660 the fuel economy is for sure the same if not better esecially when I was towing out my moose .. i'll find out the weight of it today(it'll be at least 550 lbs. and my buddy's weighed in at 666lbs.).
the only real down side I found was the rhino got high centered once that took some bigtime winching to get out and I think my wheeler would have either rolled or I could have pushed it a little easier while winching but all in all the 12 hour ride in (probly more like 10 because we stopped to shoot squirls, ptarmigan, a porcupine, and a rabbit or two). And on the way out was another story it was more like 14 hours (thanks swamp buggy for making an ungodly amount of 4 foot deep nasty rutty trails that were passable before and now are nearly impossible to get through...) so our first 10 miles took nearly 3 hours.... Then Monument was not fun at all wow.
But the end result is my buddy is thinking about getting one as well so we will see..
