David, sounds like you want a "tray ladder" - can be found at B&H, Porters or Calumet (click the link above for them). I have been playing with the idea of one of these for some time for 11x14 or 16x20...then talked myself out of processing very many 16x20's. Would still consider one for 11x14, I can get 4 trays this size in my sink, but then if I wanted to do 2 trays of fix..well you know the problem. May just get a print washer which should help ... space, it is a darkroom workers best friend or worst enemy...
