Engine Removal

I have some friends that own a 1991 motorhome that is built on a Chevrolet P-30 chassis. It has the 454 engine that has failed. I am an ASE master mechanic but I don't see an easy way to get the engine out of this thing. My best guess is out the driver's door after removing the steering column but I'm not sure. I don't want to start this project without knowing. Any help would be appreciated.

Danny, though I’m not an engine/chassis/driveline guy (my expertise has the house portions as the focus), I have seen shops struggle mightily trying to remove the block. A lot depends on the design and construction of the front cap. In some cases, the entire cap, or a portion thereof, can be removed so the engine comes straight out the front. Other times I’ve seen them raise the motorhome and drop the engine down. This is effective if the front portion of the frame has rail extensions that can be removed. And as you mention, up through the doghouse and out through the driver’s door with a cherry-picker. I don’t envy you one bit! It’s a big job however it comes out.
