Hi, ddeyoung. Welcome to the forum.
As you're waiting for somebody to respond, you may want to take a look at this old thread in the Monaco Owner's Forum
discussing a similar problem. One participant on the thread has a 2006 Holiday Rambler. Others have another Monaco product which may or may not have the same or a similar stair cover configuration as yours.
