Ah, that is almost 3/16, so they really do hold them to a high standard. Thanks guys for doing the math for me.

Realistically, I could have used 1/8 inch wall for this one, especially since I went 2 x 4, but I just feel better with the extra thickness there. (Well, I'm not feeling so good about it this morning............every muscle is hurting from lifting that baby last night, and it keeps getting heavier all the time. ) We were laughing about it last night because it took four big guys to carry Dan's frame one time, and they were straining. We might err on the side of heavy when we build these things.
