Well I'm impressed with the capability of this longer machine. It will crawl through anything my shorter wheelbase T4 did. Now on a real tight incline to a river bed with a S curve up to a hill I had to make a 3 point turn. Everyone we ride with is also impressed, at first sight they were asking where my flashers and back up alarm were! Lol now there amazed. With the entire bottom being metal it glides over obstacles. It doesn't have the low end grunt my T4 had, but as soon as the Rpms come up , there's no difference.believe it or not it seems to be a lot better on fuel compared to my 550 Grizz. My t4 was a gas mizer also. But I gladly gave up my power diff for the quietness and better ride/ more cab room of the viking.
