When I removed my cab I had it completly gutted...glass, doors, seat...EVERYTHING. The lighter the better. It took three of us, and it was a pain stepping over the chassis and what not. One thng you can do to make it easier is lift it and then push the chassis out from under it (if it is rolling)...that way you can avoid possible scraped, smashed limbs, etc...
One more thing...the front of the cab is the heaviest and causes it to be ackward to lift...sort of like a big TV. Use more man-power up there....the back is a one person job easily.
Dont forget to unhook brake lines and steering...they can easily be overlooked, oh, and drain the brake booster to avoid any mess.
Hope this helps just a little more.
