i'd say if you are going with something that old then find one with longtravel.. Although i am not sure the Rhinos are fast enough to really use it properly. At the very least look for one with upgraded shocks. Shocks are probably the single best upgrade you can do an any UTV regardless of speed..the guys seem to cover everything else pretty well.
I'd recommend always carry a tow strap, plug kit and always ride with a buddy if you go more than 1/2 to 1 mile from your TV. An added bonus would be lower doors or leg nets, seen too many people start to go over and try and put their legs out...entertaining to watch but the results aren't pretty.
I'm not a fan of carrying a lot of extra weight in UTV, hence i leave most supplies/tools in the TV and get towed back...and don't you worry, you'll break something and get stuck somewhere..everyone does... :)
