Huh, I just muled 9 long planks in two groups, oh I don't know, two (Murkan) football fields away. Economy of motion is handled OK by stacking everything you want to take with you at once, and doing the nudging process, kinda like UnReal World actually. It makes a lot of sense, economically, to lay everything down you need one by one and then carrying them off again some distance away. I said enough at 9 planks but I had all that I needed. I laid down all nine, moved on, left three behind, and was able to carry over some other useful things with ease. Those planked lids that go on the freight crates are pretty useful, they're the ones about 7 planks nailed together. Baskets and buckets go on your head of course.
