We have a Newmar Dutch Star Class A 40 ft. 2011. We have the same problem and we went to The Container Store and purchased an Elfa Basket with slide system that fits perfectly and installed it.
You can google them if you do not have a store near you. Container Store is not the cheapest but their products are fantastic, this summer when we purchased our rig we went to the store with our coach, parked in their lot and they helped us get it ready for our trip across the USA for 9 months. Well we are 5 months into the trip and what they suggested was fantastic, well worth the money and they saved us so much time.
Hope this helps. Barbara
