You can see I own several Alvarez guitars and I've never made any sense of the dating numbering system ... or even very much about the model names. Some of the guitars had an "S" in the name (such as my RD20S) but others didn't have the "S" and still had solid tops.
What I always do is contact Tom at St. Louis Music, which owns or works with Alvarez guitars. He always consults his materials and tells me, often within an hour, of any information I need about a particular guitar.
Btw, the RD20 has a laminated spruce top with laminated mahogany back and sides. It has AFAIK some sort of plastic bridge pins. I think it was probably the best selling of the RD series which were aimed basically at students. It has a 1 11/16-inch nut width. Mine, however, feels a lot fuller but that may be because of the neck profile.
