I have done my Electric cords and rope that way but in the RV, I feel that method shown is more bulky. For electric cords, I coil them in about 3 foot circle, that circle is picked up and twisted into a figure 8. Then place the two circles together and secure by your favorite fastener.
Coax cables have a minimum bending radius so I wind my coax cable to approximate the same circle as when I purchased . That is 12-15 inch circle.
I use plastic totes for most storage.
