With the upcoming cargo changes in 3.24, it would be great to have a small flatbed ground vehicle to move crates from cargo elevators into your ship. I think the MULE would be the perfect platform to base this on, as it will fit in most ships. I made this mock-up using the models from StarJump. The first version maintains the frame and wheelbase of the original MULE, replacing the box with a flatbed. The second model has a slightly longer body than the standard MULE, with the box in the back removed and the rear end stretched slightly. This version is stretched a bit further in the rear and maintains two sets of turning wheels and two sets of drive wheels.
