I can stack a truck fine, get everything to fit. But when it comes to tying down an odd load, something heavy or loose or awkward, I'm never sure I've done it right. I pull away from the dock half-listening for the sound of something shifting behind me.
More people experience this than they realize.
You can load a truck but aren't sure how to secure odd loads safely.
