Most stuff is really a personal preference thing. Roof, windshield, winch, radio and vent line extensions were first thing for me. Skid plate will be on before it really goes riding. This is my 4th sxs and I learned on the 1st one that a roof and windshield atleast for me are just basic got to have items. I had always had ATVs before so I didn't really think those were important. Until I loaded up and took it to an OHV park on a summer day lol. Between the dust, rocks, sunshine, limbs and brush I added both as soon as I got it home. Those have always been my first add on's ever since. Also these things are so much heavier then an ATV. A winch is a must. Not just for mud either.
