I've never driven a Unimog, but I have driven hundred of Hummers. I had a job driving them out of the hummer factories in Mishawaka, IN(the main plant) and the retrofit plant in South Bend, IN. We got to play on the off road track a few times. Very amazing vehicles. We drove them out of the plants and to several small towns around Northern Indiana to railroad spurs. On the highway, they'd go about 62MPH. Sometimes we'd tow another hummer behind us and they still went 62MPH. Sometimes one of the driveshafts would fall off. We'd still go 62MPH. At the railyard, we used them to push and pull railcars. While that sounds powerful, we could also push and pull railcars with a few humans(wheels on level tracks roll easily). The problem with hummers is they are so darn huge compared to a Jeep. The only problem I can see with a Unimog is they are even huger' than a hummer. /forums/images/graemlins/grin.gif
But from everything I've read and the movies I've viewed, I would choose a Unimog over a Hummer in a heart beat. Bigger truck, more capacity, better ground clearance, more attachments, 3pt hitches, hydraulics ugh ugh ugh ooo ooo!!! /forums/images/graemlins/tongue.gif
