I don't know if they can still do it or not but when I had my 1998 Monterey I called Monaco in Coburg, OR. They mailed me a manual free of charge. With the big shake up and now being a Navistar company it may be hard to get one. My Intelli drive worked just fine but did not have as many features as the Silverleaf. Then again it was paid for and I couldn't justify the price of the Silverleaf just for a couple of more options. Now my 02 Thunder has the Silverleaf and I do like it much better. Marty
