Itasca Navion bed making and sewer hose storage
We do use sheets and a quilt. When we change the sheets, my husband goes outside, lifts the door on the storage compartment and makes that side of the bed while I make the interior side. We fixed the mattress too. We went to an upholstery shop and had a one piece thick foam mattress made. It's heavier to lift, but we don't use the storage for everyday items. Because the wall was cold to touch when sleeping, I made a double layer of fleece material and put snaps on the wall. My husband says it is much more comfortable.
We use the storage outside that was meant as an ice chest to hold the sewer hose, rubber gloves, cleaning supplies for the sewer. My husband put the hose inside a thick garbage bag, replacing it as needed.
Hope these suggestions prove useful.
