My wife and I had a 2002 2902BX ten years ago. The manual that came with it was very generic mainly how to use all the systems like the stove - furnace - refrigerator. It also seemed to be a carry over from several years before the '02 model was made. I hope you can search these forums and maybe find any year that would cover what you're looking for. Only thing different with a Hi-Lo is the pulley system for raising and lowering the top.
Good luck! (in my opinion that is) Pat
