I was very unhappy when the drawers kept sliding open and breaking. Over time, all four of them ended up being re-glued with epoxy. My 2004 Scamp
has four drawers, two and two, almost perfectly opposite, across the aisle. The brace holding them closed for travel is a piece of closed cell foam from some old shipping crate, that I had pulled out of trash many years ago. The ends are modified to lock in place between the drawers. It is about one to two inches longer than the space, so it stays in place and pushes the drawers closed. It is also light
enough so it doesn't bounce out while traveling. To install it, just bend it and push it in place. It took me an hour to make, and the price was right.
