I’ve been poring over the website of technical illustrators Beau and Alan Daniels, the guys who did those daytime/nighttime cutaways of the cruise ship. One of the illustrations on their site is a cutaway of an RV, and because they show you the steps required to get to the finished product, you can get a sense of their process–and understand the labor required.
They start off with a clean, client-supplied photo of the vehicle, in something close to an isometric view:

They then retouch it into the desired configuration, with the door open, the steps deployed, and the slide-out portions pulled out:

Next they’ve got to produce the line art. (As someone who used to do this step quite often in my ID career–on far less complicated objects–I can tell you this tracing step is nowhere near as fun nor straightforward as you might think it is.)

After the exterior line art, they painstakingly do the line drawings for all of the interior parts. This would be the part of the project where I’d wonder why I didn’t try to become a doctor or lawyer instead. I can guarantee you their Layers window looked like the waiting list to get into Harvard.

Adding the color. This step has got to be satisfying because it’s the beginning of the end.

Finally, the finished product. There’s still plenty of judgment required at this step, as they have to decide how much to reveal and how much to obscure; if they got this part wrong, it would be too confusing and incomprehensible for a layperson to make sense of.

And with the hard work out of the way, changing the colors is a snap.
