Congrats Tommy! The first mod you'll want to make (unless they have already done so from the factory) is to get a bypass switch to be able to turn the speed limiter in reverse. From the factory I think mine would only go about 7 mph or something like that. Not nearly enough if you're bogging in some mud and need reverse to blast out. I also like the BlackRhino CDI box that increased the performance and raised the speed/rev limiter to allow mine to run just over 52 mph (according to my GPS).
With 27" Bighorns on mine it didn't tear up the yard too bad (I borrowed some 589's and they were brutal - probably pulled harder, but brutal on the lawn) and I only needed my winch when I got high centered. I could climb steeper hills than guys on ATV's would attempt. About the only thing I did that really sucked was jumped it about 4' in the air once. It landed really hard.
I went nuts on the mods with mine. All were great except the exhaust mods. I ended up going back to the factory exhaust. The aluminum billet exhaust tip really sucked. It made my Rhino have terrible low end power and made it run really crappy except at full throttle. I put in a Comet clutch with adjustable pucks to set how aggressive you wanted it to launch. Since I have a lot of hills that give you zero run up to them, I had the clutch set to be really aggressive. Although it would never pull the front tires, it would spin them for about 5' or so on asphalt when I stomped it. I know some guys who would have someone stand in the bed and yank back on the roll cage to get it to lift the front end, but otherwise it is actually front heavy (think about when I said I jumped mine), which is good if you climb steep hills.
I still have several of the stock parts from mine like the CDI, brand new wheels and tires with zero time on them, the stock carb, stock clutch etc. Isn't yours fuel injected? If so, that would make it about perfect. Get that reverse limiter removed, some aggressive tires, the CDI box and you'll go places you won't believe!
Oh yeah, you'll want to put you some front and rear stick stoppers for your CV joints on yours. I know you don't get snow and ice, but I shattered both of my front ones the first time I took it into deep snow. Hey, that reminds me, if you put a full smooth skid plate on the bottom and some really aggressive tires, I wonder if it will ride up on some of the mud in the swampy areas since you'll have the power to sling all the mud out of the tire tread. If you remember, mine would ride up on the heavy snow we had. It wouldn't do that with powder type of snow, but with the heavy wet stuff it was almost like a snow cat.
