I’m also a fan of the chain sinnet[0] (or daisy chain) - works really well for storage, including semi rough handling such as tossing in the trunk...
Here is another guide [1].
Note that for longer lines, it is helpful to first fold the line in half to shorten. Also works great for extension cords since both the male/female end are handily together [2].
