The first thing I did when I undertook this challenge, was to access and print out one of the sets of instructions. That guide told me to drop the front - right axle, to remove the fender liners, and to do several other things. As far as removing the fender liners, there is plenty of room in the engine compartment without removing those. I had no problem reaching anything. Things I couldn't quite reach from the top, I got from the bottom. I should mention that I have the front wheels of the coach up a foot or so on wooden ramps I constructed.
Where I must really disagree with the guide was in the lowering of the right side front axle. I could not crack that axle nut and didn't do it. However, and following the suggestion by C Boyd on this site, I went in through the starter port and took out the three flywheel/torque converter bolts, turning the flywheel to get at them with a big screwdriver. The bottom line is, using this method, I got the old engine out and the new one in with no surprises. The whole engine only has to move forward an inch or less in order for the flywheel to clear the transmission and for it to raise out of there unobstructed. Going in with the new was similar in reverse.
The hardest thing was in constructing the 2x8 gantry, and in modifying the Harbor Freight trolley to roll on it. As far as what you have to take apart in the coach, I have to say it's many fewer than I expected, and the whole project was much easier than I would have predicted.
