I've got about 500 lbs of dimensional lumber framing mine out and this is screwed down (multiple angles) to four sturdy sawhorses. The sawhorses are weighed down with, I'd guess, about 300 to 400 lbs of fresh cut logs on each corner. I've also chained (3/8 ths) the main framing to a power pole upwind. I still fret if there are high winds and can't wait to get the shell and chassis re-united ASAP.
