if your looking into more fun than work but still plan on doing some work get a Yamaha Rhino 700, its a well proven machine small enuf to fit in tight places and tough enuff to do work.

I own a Rhino 700 and I work the hell out of it all year plowing snow and mowing grass and Im still able to enjoy just horsing around with it as well and I have yet to find a problem with it or have any kind of trouble.  In my opinion I think its the best all around UTV.

   The RZR-S is hands down with out a doubt a sweet ride for sure but I have to ask, What do you hunt?  :idea: If its anything bigger than rabbits and birds you may want to think about something with some cargo room in the back. (ranger, rhino, teryx)

Rock crawling? Unless you thinking about lift kits and rock sliders Id be looking for the most ground clearance you can get, My Rhino is 12+ inches and it bottoms out and rubs on everything when im in the woods. 2 inches less is alot when it comes to rocks and stumps.

Ask ruthlessmotorsports he may be able to set you up as well.

2X4 will work fine on trails and dirt roads like everyone else has said but if I were you I would invest in a winch and a few tow straps as well for sure, You never know what you will get into. 

So befor I found out that the state of Maine would not let a Rhino become street legal I was looking into geting turn signals hooked up, now since it would be a waste of money I thought I might as well share the plan I had come up with for my tail lights.

You can get a converter for trailer lights. what it does is turns brake lights into turn signals, brake lights will still work like normal but it seperates the turn signals left from right. (so both lights dont blink at the same time) but still alows for the use of hazard lights. This would be simple to use on a side x side and it shows how to wire it right on the converter it self, this would save hooking up and mounting an extra set of lights on the rear just for blinkers.
This is a very small box and is only about 1/2 inch thick, water tight and comes with 3M tape to hold it in place. I got one about 10 years ago for a trailer and it still works great. I think it cost around $20-$30.

I think this turn signal switch has the converter built in but will take a little more time and wiring to install.

I was thinking some heavy tierod ends like this would make a great disconnect for the back of my Rhino.

I tow a DR mower in the fall and still want my rear sway bar for stability on side hills but want to be able to disconnect it when i go into the woods.

I talked to the tech that works for my cousin this morning and he has fixed a few of them and says that once they pop out once it can damage the gear or the tip of the shaft so that when its reinstaled it will not fit tightly. he has replaced the shaft and gears on a few machines. he said most of them were on the 1000, Big tires and lift kits make it worse. Sounds to me like there should be a free air vent put in 3/8 or bigger

not much help, hope it all gets worked out
