I am just about to hit a year ownership of my rtv x1120d. Around 300 miles and almost 100 hours. I'll hit the high points first, as they really shine with this machine. First off, its built to work and built to last. I use the machine every day for general farm chores on my vegetable farm. With the rtv x you get a proven kubota power plant, that when used in industrial applications, can easily.last 7,500 hours of use before any major work is needed, thus the motor is a lifetime purchase. The frame and skeleton of the machine is built to match. Full osha certified ROPS that will save you if you tip, quality tractor-like frame build , steel bed. And then the transmission, which is another tractor style and quality component that is meant to last a lifetime of ownership, not to rocket your son and his friends 50 mph down a dirt road. I actually use my utv for work so the coast-to-stop feature is highly desirable for hopping out to take care of something real quick without having to lay on the brakes. Also great for traveling on steep hills, particularly down them.
I've put the rtv through its paces off road and unless you are buying a utv for the SOLE purpose of flying down trails I fail to see how one could be truly disappointed with the rtv. I've pulled a fully 8x12 dual axle trailer overflowing with wood mulch out of a hilly, muddy, and treacherous PowerLine easement on my property. I use to get around hunting camp, I use to show my property to friends, and it handles off road just fine. Does it like soft mud? No. Due to the beefiness of the work features the machine is over 2klbs, outweighing even the largest Polaris by nearly 800 lbs. So don't go charging into a mud hole like you see on these youtube videos and expect the mini-tractor with small wheels to come out.
I love mine. But it's a machine I put my butt in every day and I need it to turn over and work and work right. And if I wanna go have a little fun with it during hunting season or on the weekends I want it to handle that, too. If I was just going to have fun and no work, I probably would have gotten an 825i, but considering my uses I have never once regretted my decision.
