Here is my solution:  http://www.target.com/p/cosco-adjustable-height-activity-table/-/A-12759974#prodSlot=medium_1_21&term=folding+table 

Use inside and out, lightweight and folds flat and adjusts like an ironing board.  Takes up much less storage space than the stock table but is larger.  Since I've also removed the top bed, it stores in the fold of my 3" memory foam topper which is now kept up there.

After 20 years and just the two of us now I'm running lean and mean with shelves where the fridge was, no stock tables, and no upper bed. Oh, and no rear heater or A/C either.  Storage space is more useful to me.
