What Dan said. Seems most of the rear slide "expandables" have bunks. The 21RE s a nice unit and would certainly offer you what you need and not a bunch of stuff you don't need. Agree that it was a limited run, but don't know what years. Find the Forest River website/Rockwood Roo and they may offer some pictures of the inside. If not there, just start googling the model and there will be dealers that will have pictures. Know going in that rear slide models, especially without the bunks, are not going to be on every corner. Don't know which FR factory built this model - might start with Millersburg, IN - and ask them for a list of dealers who have ordered this model and also the years it was produced and start checking. Good luck.
