Understand getting rid of the MoHo. We only had ours for seven months. Left AS and now are back. Don't have what you are looking for but good luck. Check Colonial AS, in Lakewood NJ. They are the or one of the largest dealers and often have a large variety of used AS in stock. We bought a 25' from them several years ago and aside from being too small for us we loved it and it was in the exact condition they advertised. We bought it over the phone and internet and drove down to pick it up.
