I purchased 2 ottomans with reversible tray tops. One acts as a console between our MH captains chairs while driving, tray side up. I store blankets and sheets in them. Ottoman, storage, side table - all in one.
I purchased 2 small, round, metal folding tables at Wal-Mart. One is for a sofa table, one goes outside by the door, (great when you return from shopping and need a place to park something while you open the door). They store, folded up, behind the J sofa.
Linens and Things sell a cushy liner for cabinets and drawers. I cut circles out of it and put them under and between plates, bowls etc. No slippage. It can be used under the coffee pot while we are travelling, I use a place mat size piece when making sandwiches and drinks while rolling down the highway, it keeps jars, knives, etc. from sliding around.
I saved 2 cardboard drink holders that came from a fast food take out restaurant to hold glasses in place. No slipping, falling, tinkling or breaking.
I bought 2 plastic drawer units (3 drawers each)and 3 stackable open front storage bins for our closet. The bins are for shoes, the drawers are because our bedroom only has 2, one for each of us.
A 3 tier wire corner shelf inserted into a ktichen cabinet fits all dishes and bowls.
A tp holder that stands on the floor and holds 4 rolls - saves a lot of cabinet space.
A laquered tray on the DR table holds all the stuff that we need, but not this minute. Pens, keys, chargers, emery board, etc.
All white sheets, towels, etc. makes laundry day easier. Less sorting and fewer machines to use.
In the wet bay, I store rubber gloves, hand santizing soap and liquid Lysol spray disinfectant in a clear plastic shoe box. Screw a paper towel holder to the wall in the bay and you can wash up after every dump immediately.
Cheap garden solar lights for the front door area, at the hook-up pole and at the edges of the slides help a lot!
By far, the best is the pistol grip flashlight I bought at a Pilothouse Truck stop. It is a disposable, but lasts a long time, is small and powerful enough to shine on signs at night so we can read them. Under $5!
