The storage bays on our High Country have a lot of "vertical" space. In order to utilize this vertical space, I made a few "cabinets" that give me a defined place to put certain things and also allow me to stack those things to utilize that vertical space. The cabinets are movable - not attached to the floor. They can be removed for cleaning or service in the bay areas. They are heavy enough that they don't move around during transit.
Door side storage bay
. The cabinet in the middle holds a couple of chairs, Bar-B-Q tools (dirty storage), and has a drawer for small items. This cabinet also serves as a "bookend" for the stuff on the right side of it that stand flat, on edge. Chairs, a propane stove, a step stool, folding tables, etc. Those items are separated by sheets of lightweight thin plywood just to keep them apart and from hanging on each other when they are slid into their space. The tub on the left of the cabinet holds frequently used miscellaneous items.
The fuzzy covering on the basement wall holds the loop side of velcro well, so I just use a loop of it for hanging things that need to be easy to find.
Front storage bay.
one "layer" removed for the sake of the picture. Like a lot of folks, I use stacking tubs. They end up migrating to the least used on the bottom, the most frequently used on top. Fishing poles are mounted on the wall behind the tubs and are well protected there.
Another shot of the fishing poles. The holders are foam/friction type. I think they came from Walmart.
Another shot of the front bay with all the stuff in it. These items in this layer are usually removed at a campsite first, so access to the remaining stuff is easy.
Left side storage bay.
Open-ended cabinets are used here again to use make use of the vertical space. On the left side the cabinet holds a folding canopy, a folding aluminum table, beach umbrella, and my "calibrated stick"
. The calibrated stick is a wooden measuring stick that has depth marks for the bedroom slide, the main slide and the kitchen slide, so when we initially pull into a site, we can easily measure our distance from surrounding objects like the power column, the water faucet, etc. The full length of the stick is the hitching height for the pin. The cabinet in the center holds the portable grill and allows a satellite dish to sit on top. The cabinet stays in the bay when the grill is removed for use. The rest of the stuff in the bay is housed in tubs. One for water hoses (sits in front of the cabinet), and another for water and electrical adapters.
Water hose storage.
Water hoses are stored in a tub with plywood separators to keep them from tangling. This tub travels in the left side storage bay. I connect the hose ends together when they are coiled to keep any residual water in the hose. The tub keeps wet hoses from getting the storage bay floor wet.
There's nothing unusually innovative about these storage methods, most folks are using some variation of them. But, these have "evolved" over the years and have worked well for me. Of course, they never stop evolving as we add more "stuff"!
