Well, we finally got the Uforce800 out for some trail riding. Had a great time and the machine performed flawlessly. We hit some steep uphill and downhill sections the were nothing but big loose rock and silt, some deep waterholes, deep ruts and lots lof loose wet mush. By mush I mean silt like material and it took it all like a champ. Only casualty was some scratches on the passenger side of the bed due to sliding down in a rut against a tree but it was only cosmetic. I was plesently surprised that during this whole ride I only had to use 4wd for 10-15' while following a tight lil trail around a huge water hole which I got partially high sided on. Low range powered us around the tight places with no problems. Boy do I love this machine.
