We spotted this on a Coromal Seka caravan. On all A'van there is a "dead" area directly in front of and under the sink. There are two options here. You can make a special draw with a cut out to clear the drain pipe. This is great for knives and other cooking bits and bobs. The second option is as per the photo of making a shallow cupboard. This could be ideal for spices, vegemite and other small jars.
