Well, yeah, Mav, I read that part. But having sat in more than one dozer, I'd think that the dude would have passed out in about 45min. to an hour in that thing. Plus, you'd have the exhaust fumes leaking in (The turbo-to-exhaust seal on a cat will leak when they get old) And I'd think he'd be overcome by fumes. Heck, I saw a guy on a D9N, about 23 and in good health, actually pass out at the controls, with just a regular cab. The exhaust was leaking really badly because of a broken pipe joint, and he had an enclosed cab with busted AC. I'd think that an armored hood would make things alot worse. I'm thinking that he would have expired in there anyways...
