I own a Gator XUV 855D w power steering, power dump, deluxe ROP's and glass doors. It doesn't feel under powered by any means although it's top speed is limited to 33 mph. It has good low end power and sips diesel. I checked the tank when I first got it several times to make sure the gauge was giving the correct reading. The most load I put on the machine is pulling a 66in finish mower and it handles that with ease. The amazing part to me is the quality of ride. It eats up ruts, hills, and rough terrain like a Caddilac DeVille doin 60mph on a gravel road.. Just floats along. The cab is loud w the doors on but open cab is no more loud than my friend's Polaris RZR. Been a solid workhorse for us and offers a great off road suspension set up for trail riding. Feel like we got the best of both worlds.
