Welcome to the forums and congrats on your decision to purchase a Montana.
I can't make specific comments about your model, since i don't have one, but if you jump over to the Montana Owners Club, here is a thread about your model asking similar questions.

Actually, I favor 3 different forums. I'm not sure if they are run by the same parent orginization, but i do know my user ID and password use the same system (I think).
I've used this forum for lots of reading on Keystone issues for years now. I didn't start actually posting until just in the last year, but I'm on my 3rd Keystone camper now. Actually 4, if you consider Dutchmen, but that was before Thor Industries acquired Dutchmen.
The second forum is IRV2
Click here. This forum site focuses on Motor Homes, but it's chocked full of information, and there sub-forums for travel trailers, fifth wheels, and so on. Good info.
The third, is the Montana Owners Club forum. I like this forum because it's specifically everything "Montana". And folks there know the Montana product.

Again, congrats on your decision, and see you on the forums ... and maybe someday, at the campground!
