As a previous poster said, you should be able to get one by calling Heartland Customer Service. The newer models are now called Country Ridge due to some confusion with another manufacturers model names. The FK is a great floor plan and if we ever buy a park model it will be that one.
Keep in mind, the owners manuals are very generic in nature. It might not give you some of the information you're looking for. If you do need help with something specific you can ask us here on the forum or go into the Country Ridge section and use the Ask the Factory area. They usually respond within a day depending on the timing of your question.
Another route to take is a call to your dealer for specific questions.
