I am getting ready for camping season. I want to build my own chuck box instead of buying one. I am having trouble finding plans for building one. Any suggestions?

When it comes to camping experience and outdoor ingenuity, one name which comes to mind is the Boy Scouts. With a little searching I found several plans for chuck boxes.

Chuck Box Plans
Four different plans from Troop 168.

And Ken Ralston has a variety of plans, kits, and finished chuck boxes available at Blue Sky Kitchen.
