This is a crate (aka Diablo Town Trunk) that I made for camping.  Benefits include...

• It holds 19 cubic feet of storage.
• Mounts on the back of the truck and rides firm without rocking (requires good straps that winch tight of course) and leaves tail lights exposed.
• Top is a great workbench or kitchen counter.  I use it as a workbench even when not camping.
• Fold out front surface makes a great serving  table or additional field kitchen counter. 
• Roxanne loves it as a field kitchen. She likes it much more than the Coleman folding kitchen cause it doesn't wobble and she can easily turn the grill around to combat wind, and offers much more surface area to prepare food.
• Blends in with environment.
• Also a great bear box (untested, and hopefully remains untested).
• Can function as a dog house or make shift shelter if the tent is destroyed.
• Plenty of tie downs for bungees, which can also serve to make a towel rack as shown behind her arm in the photo.
• Top and front load.  Front door is required to reach the floor.
• Makes a nice bit of shade for the cooler and dogs at sites that lack shade.

I built this because this year we wanted a larger tent to store our stuff, and tall enough to stand up in.  But we are already at max capacity in our little SUV and I still wanted room for our kayak gear as well.  So rather than spend 6k on a good off road trailer, this was my solution. 

Like any project, I tried to see how many problems I could solve in one design.  This has proven to be the most impressive single piece of gear we have.  Even more so than the new cool tent (reviewed later). It's not as vital or important as food and shelter, but it's the most impressive with the number of cool useful features.
