I would like to find a way to install a tool box inside my tractor cab. Nothing big, just something to hold things like plyers, a vice grips, a common sized wrench or two, wire cutter... Things you might need out in the field. I wouldn't be against mounting it to the outside but obviously it would need to be water tight and lockable. Just wondering what you guys may have done with yours. Oh, my tractor is a MX5400. Thanks.
