Can't say I can live up to Rockin's view of my storage compartments but will try.
Having an older unit...my storage is smaller than the newer units and the height isn't as high. I also have the metal generator box in the front...and have wondered if the box wasn't there if the front storage would be bigger.
Tool storage on one wall...looks like I travel to do landscaping while on site...but. The plexiglass window was added, no sliding door, to keep an eye on the 'stuff' going on behind the panel. Can easily see the tank and hose. Have a moisture monitor there as well as the other side with the water pump.
I made all my hangers in this area using aluminum flat bar material, should be able to get from Lowes/Home Depot or other hardware store. A hacksaw and file to make what one needs. It's easy to cut and bend to make a hanger for most anything.
The tools/handles for the spare tire and manual crank for the slide were hung on the compartment door...always in the way. Moved them to the frame and in the corner out of the way. These spring clips do a good job of retaining the items and if a hook isn't needed....
Left side of front compartment....carry a torque wrench, tool box is a film canister storage box I found. Drawers are deep and provide plenty of tool storage and the height allows room for two small tool bags that carry bosch drill, driver, flash light, charger items from the shop and a small portable bag with the meter and 'quick responce' tools.
Have a small pouch storage for things I don't use often enough but have easy access. I installed a 12' deep wire shelf about 4 inches from the top and it has worked well.
On the right side, I wanted a shelf and needed something that didn't take up a lot of space with the frame. I determined what I needed to have and made a shelf out of 3/4" ply, rounded the corner to keep from hurting myself with the edge and wrapped it with a 2" aluminum flat bar to retain the stuff. A 3/4" aluminum pipe/tube was used as a single leg to support one end of the shelf. The back and right side are supported by two sections of 1", 90 degree aluminum angle that can be screwed to the metal box. The shelf is then screwed to the angle. Takes up little space and is light in weight.
I hung the extention pole I use to wash the bugs off using two hooks. There is a smoke detector on the ceiling, have one in each compartment and been think of adding one to the back of the Refrig compartment...still thinking.
If you can't find the hanger hardware you want...consider using some aluminum flatbar. It has worked for me.
