Now that IS impressive! There are some issues though. We specialize in American military trucks... Unimog trucks are a different category of truck (I could be wrong) but it seems to me you couldn't compare a truck like this to 5ton, which has three axles and is a bigger truck. I don't know that one could even try to put a 6,000ltr water tank on one of these,,, or could we? I'm not putting down Unimog though, they gotta be good trucks, just that they don't work for what we need as far as I know. "I don't pretend to be a truck expert BTW, I realize I could be wrong"
