This is a really nice Keystone Montana high country. It has the bunk room in the back also called the rear den. The unit is in really nice condition. The outside kitchen has never even been used. My husband did add bed railings to the bunks in the back. We have not made any other modifications.The tires are in great shape, as we have not driven more than 2000 miles on them. The unit still has a couple years remaining on the warranty service contract. Any questions please message.
