I thought of this myself but I rejected it as a possibility, since he said he already had MCD's, and I figured if he had MCD's, he had TIGER, and thereby the unincorporated CDP's, as well as the unincorporated MCD's.

I would think a truly exhaustive answer to this question is impossible.  Does he want every town name that has local meaning?  (Things like Mechanicsville (a neighborhood of Knox County, TN)?   Every defunct town (whose borders may have changed over the years) but no longer has legal status?  (I'm not sure if Mechanicsville was ever in that category or has always been a neighborhood.  Maybe Grover's Mill, NJ is a better example as a town name with local meaning...)  Every neighborhood association with a restrictive covenant/elected committee members/bylaws?  Every trailer park in the USGS "populated places" layer (just a table, not GIS)...every trailer park not in that file?

You might try the Census Bureau's collection of boundary files.  I don't know of any maps that show just what you are looking for, but with any basic GIS you should be able to use these files (Incorporated Places/Census Designated Places) to find what you need.  When using the  Incorporated Places/Census Designated Places file you need to select on LSAD (short for "Legal Statistical Area Description") equal to "57", or select on LSAD_TRANS equal to "CDP" (short for Census Designated Place).  These are defined in the Census Bureau's online glossary as "A statistical area defined for a census as a densely settled concentration of population that is not incorporated but which resembles an incorporated place in that it can be identified with a name."

To date I have only been able to find boundary maps of counties, mcd's, and the like, but I really need good boundaries for the unincorporated areas as well.  Any help on this subject would be greatly appreciated.
