The love of mobile storage
Use as much rope as you need, and do not worry about using too much. Also practice knots beforehand so you are certain that your knots will not slip. Otherwise, you could crack the container open at the end of the journey to discover that the ropes worked loose and all your things are in a jumble. As you pack the moving storage, remember to concentrate the weight on the bottom, not at the front. Make the contents of the unit completely immobile with padding, or get the same effect by roping it down.
