We've made just 3 "improvements" to our 2011 20' Flying Cloud. The first was installing an aftermarket "shelf" to the underside of the cabinets above the bed, making a great place to park glasses, flashlight and other small miscellany for the night.
The second was installing a light at the "foot end" of the bed to provide flexibility for reading.
The third and, to my mind, the best improvement has been the addition of this shelf. It sits on the partition at the foot end of the bed and provides an out of the way spot for our mi-fi, Sirius radio, and cell phone charging. When we're watching tv, it's a great place to hold a drink. The neatest thing about this shelf, which my husband made, is the design. It consists of two pieces, the shelf and a bracket. The bracket is held in place by two Command Strips, so if we want to remove or reposition it, it's quite simple. Now if he would just make another shelf for the head of the bed. :-)
