I am well into my 30s (have been for over 30 years) and I can roll the cab on its front by myself with 2 eight foot long 2x4s attached to the firewall by nuts and bolts going through existing firewall hole. The beauty of this is that no part of the cab ever touches the concrete floor. It is protected by the 2x4s.
If you bolt the 2x4s so that they are 4 inches shy of reaching the floor, the cab starts to roll much easier than if the ends of the 2x4s are touching the floor.
I can also lift the cab back upright. If you have a long enough lever, you can move the Earth, someone once said. Copernicus maybe, or Moe, Larry or Curly. I don't recall.
