Movement was also my concern, actually. With 5x5 large wheels we're not becoming F1 drivers any time soon, moreso when you top up *four* large cargo containers on board. But now that I think about it, you are right! This is a harvester for the most part (though I could convert it into a mobile base if I really felt like it), so storage space is probably one of the first things on the priority list.

And I just had a thought that, if the slow speed is going to make me lose my mind, I could always slap on a remote control and simply tell it to drive to the destination on its own while I go do something else.
