Below is a pic of part of the old cage sitting on the frame... this is just for rough measurements. This thing will be a flat bottom rig and I was thinking about making storage compartments under the floorboards... I'll be able to put supplies, food, parts, tools etc... I'm figuring the compartments will be roughly 8" deep and how ever long I want them. Heck, I Might have to make one into a beer chest... lol
