Not sure if you are aware of another forum which is dedicated to owners of Keystone Montanas. Check out www.montanaowners.com
We have a "social group" of Montana folks on this forum which you can join. To find out more about this, look at the blue bar at the top of the page, find Community, click on that. A drop-down window will appear with "Social Groups" as an option. Click on that and follow the tabs and links to the Montana folks social group.
If you have any specific questions related to your Montana, find the most appropriate categories here on the forum and post them there. You'll get a better response rather than posting them here in this section.
