We have a very small fifth wheel so storage is always a challenge. Our interests, archaeology and biology, take us far and wide and we are often far away from stores for days or weeks so we try to stay organized and prepared. We use soft side briefcases, bought at garage sales and thrift stores for $1-5, to organize and store many necessities in the truck and trailer. They are durable and very easy to stash-we have the basics: first aid, picnic, tools, etc., bags in the truck and trailer. We also store store reference books, maps, camera gear, biology and archaeology materials, grandkid toys, etc., in the bags, as well. Each bag is tagged with it's contents. This storage method is certainly not decorative or "cool" but is incredibly useful and serves our needs very well.
