Peter -
The numbers that Bird came up with support your suspicions. The safety factor seems to be about 2 to 1, and you can bet they're being conservative on the ROPS data plate.
I sorta thought this had all been worked out, but I always feel better with a few facts and figures under my belt. I guess that's the engineer in
me. [img]/w3tcompact/icons/smile.gif[/img]
