Hi Jeff. We also use plastic tubs ("Safeway", "BWS" and Kitchen) All containing what you imagine would go in under those headings. Spare Bedding is also in a plastic tub along with lesser used or spare bits and pieces (not tools or car spares though as they have their own spaces) in another. Electrics (fluoro lights, cords etc) in their own "electrics box" go in the tool box. We also each have a smaller plastic container for personal items like cameras, spare batteries, medications, etc which travel accessibly in the vehicle. The tubs keep everything together, people know where to begin to find items and help to make packing and stacking easier. Just a case of trial and error until you find what works best for you.
Cheers,
Sue
