Casey the RZR 800 and 900 are the most powerful on the market. Just get ready to spend big bucks. You don't want a RZR because it doesn't have power steering... You'll need it pulling the truck. The Ranger 800 like I have has power steering, efi, and a bench seat. Buckets suck getting in and out of in a hurry! The buckets are way more comfortable for long rides, but the bench is the way to go if its a hurry hurry deal. Plus, you can fit more in the bed of a Ranger/Rhino and fit another person on the seat.
