For current models the suffixes are King or Queen (rear bed) then Sofa, Dinette, or Bed so a 2720QS is a 2720 with queen bed and a Sofa on a slide out in front. Older 2720s used just plain 2720 for the Bed front and 2720SL for the sofa slide. I have not seen the early designation for a Dinette.

AFAIK only the 3326 had both a dinette and both front and rear bed though the dinette in most models makes into a bed.
