I admire the functionality of the drawer systems I see in people's rigs. I've seen very high end systems and DIY systems. I only go on camping trips from time to time and may venture into overlanding in the near future. What I am wondering if whether the benefit of having a "system" of some type in the back is worth losing the flexibility of just an open cavity of space that can respond to any hauling need. Thanks in advance for sharing from your experience.
