Examples are never necessary if the rules are complete. But they can still be awfully helpful. There are quite a few possible cases: different relationships of the mech and towed object before the move, different terrain features such as Oil Slicks and Lava Pools. Some people understand the rules better through a bunch of examples.
I share your pain. The box is absurd! I was trying to fit it onto the passenger seat of my car this afternoon, but eventually gave up. My solution was to attach wheels to the box and just tow it to game night. My friend suggested a "wide load" sticker just to be safe. Worked beautifully. Looking forward to playing with this giant toy tonight.
