Did you drill a bunch of holes to make this happen?
You are correct that the shell skin has little or no meat for it to rest on the sawhorses. Here is the set up: sawhorses with 4x4's spanning under the shell, 2x6 vertical spacer blocks attached at the bottom to the 4x4's and attached at the top to the 2x6 horizontal cribbing. The horizontal cribbing is attached to the shell ribs with carriage bolts. Yes I did drill holes into the ribs to attach the cribbing to the ribs with the carriage bolts.
For the end caps the C channel stays attached to the shell but the shell skin actually hangs down over the channel so I had to put small 2x4 spacers between the bottom of the C channel and the top of the 4x4's. I also used the vertical spacer blocks to attach the 4x4's to the cribbing.
