Have a 09 lifted Ranger Xp here in Alaska that is awesome. It can a haul a full moose and camp over some steep mts with ease and it is only a 700cc. Just bought a 2011 Robby Gordon RZR 4 to play with in winter in Yuma. Has 2700 miles no upgrades, any suggestions besides roof of course? Also any common problems besides sounds like checking diif. nut? This will get me by until hopefully I get a new a a few years. Good riding to all!
