    If it's practical the flotation would be superb on soft ground. Would you want to move the rear, ahh, front axle forward to take some weight off the steer axle for maximum effect?
    They seem to have the issues of the extra axle pretty well figured out:

    Nice.

    They're dividing the drive before the middle axle so both rear diffs are receiving equal power so you'll always have at least one wheel on each diff turning, unlike a truck.

    They mentioned making use of traction control which is no good to those of us that are stuck in the past (or, should I say, clinging on to the electronic-free days of reliability and repairability!) But that shouldn't matter too much; you'd be unlucky to get three wheels on separate axles hung up at once and then it's nothing a diff lock or two couldn't fix.

    Even with three open diff's you'll still have an advantage over a 4x4.
