No direct experience, but a few years back someone posted pics of removing their engine from inside the RV using a cherry picker. IIRC, they placed some plywood on the floor and lifted it up through the doghouse opening and out the door. When we had our previous rig (97 Winne Vectra, 460 CID) I check out the openings and thought if I ever needed to do that job that's the approach I would take. However, your HR may not have the same clearances. Fortunately for me it was never required. Good luck and keep us informed on how you tackle this.
