We have a 19' Bambi trailer and have the same issue with no place to store glasses, books, flashlights, etc. when in bed. I took curtains that have the large hole at the top for hanging through curtain rods. I cut them down and sewed material in front to make pockets that will hold glasses, books, pens, but not coffee cups
Then I took a large S hook and hung these from the curtains in the camper ( 2 hooks per). I made 2 of these to place on both sides of our bed for each of us. They are handy and won't be in our way when we get in and out of bed. Enjoy! Michelle
