Many dealers are worthless in terms of practical use of a RV. Since you are new to 5th wheels and Montanas, I highly recommend you join the Montana Owners Club (MOC). This is a free to join, non-vendor owned source of information for all things Montana. All you need to to do is select a userid/password and you have access to over 15,000+ other owners and their collective experiences going back to around 2000.
With a 2004 Montana you are going to need some assistance that the dealers can provide when things go wrong. You have now found the mysterious third grey tank handle. Other common but frustrating problems are "slides stopping when opening or closing", "toilet bowl won't hold water" and "decals are peeling". All of these issues, and may more, can be answered there.
