Basically the pipe ends up being brittle, and in a roll-over it will shatter
rather than bend, so you end up getting no protection, and possibly having
shards of pipe protruding through different parts of your body. Fun right?

The guys that build tube-chassis buggies for rock-crawling tend to use
1.5-2" OD tubing with 0.120" wall thickness. Good for strength and weight
overall. But these buggies also weigh in excess of 2000 pounds, up to even
3000 or more.
So, we all seem to be looking at building a machine that will weigh in
(including driver) around 1000 pounds right? I'd suggest 1" (or even 1.25")
tube with a 0.120 wall thickness, and that would definitely be damn strong.
When you layout the structure, traingulation is a definite must as well, and
you can put in little gussets to help in the corners and increase the
strength of the structure.
