They Keystone Owners Manual is a "generic" and it is placed in all of the Montana units. You have suggestions above on what to check out and I might add you can also join the Montana Owners Facebook page and find info there also. The best way to find out specifics is to ASK here on the Forum. You have experts here that can give you answers to nearly all questions you might have about your unit and it's workings. Welcome aboard and think about joining us at the 2018 Fall Rally in Goshen, Indiana in September(see the posting about how to sign up here on the Forum) and you will get all kinds of info at the Fall Rally about your unit and a whole lot of helpful folks that will answer questions you might have also. You can also attend any of the Regional Rallies, also posted here on the Forum under Regional Rallies, and meet more MOC members willing to help and answer questions you might have. Welcome aboard and hope you enjoy that unit
