This is the inside of the TX case. Lined the top with hospital bed foam, and filled the bottom with great stuff expanding foam and trimmed it as necessary. Hope I gave you some ideas. Again, I suggest making something on wheels. It's amazing how much a little pine, fuel, a battery and some tools will weigh. Good luck. Feel free to drop me a line if you need some help. Woodworking is my second hobby, and I love to design stuff.
