Hey Steve! I’ve done it. It’s not that hard if you have a good work area and some good jack stands. Essentially you’ll raise up the entire coach by enough height that the cradle can be rolled out once it is lowered. Pay attention to the brake lines, fuel lines and wiring; and be sure everything is noted and labeled once disconnected.
To roll it out, I placed the drums on wheel dollies and maneuvered the cradle with a low profile jack.
You’ll also need an appropriate socket for the six cradle bolts. Be sure to spray them with some break-free before attempting.
