I've got an RTV 1140 and love it...the extra seat is soooooo much more handy than I thought it would ever be. I leave it set up all the time. Good place to put certain tools, buckets, etc while moving around on the ranch in working mode...and I have a small trailer attached as well for T posts, wire, lots of big tools for specific task in progress. I did lots of upgrades as well, including front and rear lights and associated switch box which I constructed and installed.
Net...think about the 1140 for your needs....I see you have a large property, as do I....It's amazing to me how extra handy the extra seat is...can carry an extra helping hand or two while having an easily accessible place for jackets, ropes, gosh, so much stuff while dashing around and not having time to stow everything while work is in progress. It's a true ranch work vehicle...top speed of 25mph is sufficient, and more, for off road work. and, 25mph is just fine to dash down most ranch roads and get to the other side!
Not sure the 1140 has yet been upgraded with the new features. Biggest negative, and it's kinda small, is the 1140 has its emergency brake at hip level on left side....hip hits it getting in and out, particularly if it is pulled up.
