This is a remodel issue. Want to run a drain pipe in the crawl
space from a laundry room sink and it will need to be level for
about 18" just before it hits the sanitary tee that leads to the
waste line. The reason is there is a dryer vent in the way. I'm
concerned about how well that section of pipe will drain.

Your local permit office will help. Ask them if you can go 18" with no
pitch in the pipe.

Good answer.

I still like my idea of putting in cleanouts for the inevitable
cleaning-out.

Actually not a good answer. If the pipe requires a slope, then it's
required. That's it. No one will tell him otherwise, whether it's for
1 inch or 18 inches. He's going to have to mash the dryer vent a
little to make some space. Not a big deal.

Which is apparently just what the OP ended up doing.

Yet another testament to the ability to fix a seemingly hopeless
situation by a little judicious bending, twisting, jacking, pinching,
prying or otherwise forcing something where you want it to go.

The mouse said to the elephant: "if it don't fit, don't force it".!
