Not s RZR fan but we have a farm and need something more versatile, so we have a JD Gator 825i. Neighbor has a new Polaris Ranger 4 seater. He can outrun me (but barely and it takes a long stretch) but I can outwork him. Another neighbor has a RZR...
If the trailer is under 20', I'd not tell you to get towing mirrors. Otherwise, think of them as a necessity to see properly while towing and backing your trailer.
