I have the gasoline version, and just shy of 100 hours. Only problem I've add was busting the right front CV joint. But I do some serious off roading with it, hauling deer stands, corn, plot feed, camping gear, etc. in Southern Ohio on skidder trails with lots of large rocks, etc. The thing runs over 6 inch logs at 40mph like they aren't even there. The same roads have beat up pickups & jeeps over the years with broken drivelines, punctured gas tanks, broken tie rods, and the list goes on. The Gator eats up that terrain, and then gets into the "rough" stuff.
Just built a very nice tree house/deer stand up the side of the mountain. Our local care taker had a rough go of it getting the the location on his ATV, yet we hauled up 3,500 pounds of material in just a few trips, to include multiple 18 foot 10 inch wide posts.
Be sure to invest in the brush guard kit around the entire body, as it will save lots of body rash problems. The hydraulic dumb bed is great for off loading logs. Along with my 2520, one of the best purchases I've made. They even work great together, XUV hauls the log splitter, and use the bucket on my 2520 to get the wood logs, load them into the XUV, haul them to splitting location, and cutting firewood isn't so bad now...
