> place the largest boxes at the bottom and build upward with smaller boxes I think this is actually a basic rule in packing / loading. Get the big things in first and then work around them with the small things. It's how I load my car when going on a big trip. The main exception is things that you will need quickly without having to unload everything. 'Big things first' is also why mixtures (e.g. muesli) settle in transit with the larger pieces at the top and dust at the bottom. Small things can work their way under the big things but the converse isn't true, unless the whole volume is vigorously shaken.
