most of the complaints I've read from new Rhino owners can be traced back to poor to no dealer prep. Loose bolts, clamps etc.. Some of the overheating was due to too much air and not enough fluid in the cooling system. Some were clogged radiators, but others were not involving mud or even very hot days at all. Good lesson there, don't trust the dealerships mechanics with your expensive atv or uv.
The leaky gas tanks have been remedied by Yamaha I've been told. Even the folks with the break downs are very satisfied with the Rhino.
My hunting partner seems thrilled with his rhino. I drove it, aimed at the biggest mud hole and roughest stuff our lease had to offer. It was nice, loud, a little bit more vibration through the seats and steering wheel than I expected, but quite a nice sporty ride for sure.
