Hey Scott,
Not a dumb question at all.  As Kevin mentioned earlier, they really amount to the same thing.  Both are subservient estates.  Generally what I find is that it is only on roadway easements does the document refers to a right of way rather than an easement.
I don't think it is important for us as title examiners to differentiate between the two.  But if you want to quibble about the difference, I believe a right of way gives a greater easement right.  With an easement, there may be the ability to maintain structures and trees within the easement area if they do not interfere with the easement rights.  With a right of way, everything is barred.  You are also usually looking at a public right of way rather than the rights of a specific party.
I hope I got that right for you buddy.
