You might also want to imagine how you would use the cabinets/storage areas to determine if your stuff will fit. Take a tape measure with you and the measurements of any large/odd shaped item to see if that item will fit. I worried and stressed every day ours was on order that our stuff wasn't going to fit. Not only did it all fit, we actually had some empty space! Not anymore
... but we did for a little while when we first moved in
Something else to keep in mind ... if you don't like the furniture or how it's arranged or the bedspread or the window treatment ... change it! You'll be amazed at how many different decorating/storage things you can do in a Montana.
Have fun!
