It will be hard for me to tell you how many square feet your RV is. The motorhome you talk about came in two different models. They had a 38 footer with 2 slides and a 40 footer with 3 slides and unfortunately I do not know the square footage of either model.
The best place to find out the square footage of your motorhome is by contacting Coachmen Recreational Vehicle Company, LLC which is a division of Forest River, Inc. Their contact information is below.
