Travel the country in the all-new Heartland Big Country Fifth Wheel Trailer 2009. Taking innovation to the next level, the Big Country’s front cap design provides improved turning radius that offers improved turning capacity, and its large, exterior pass-through storage offers over 140 cubic feet of extra space. Inside, this Heartland fifth wheel trailer doesn’t scrimp on innovative features either. A king-sized bed is the ideal place to lay your head after a long day of fun, especially while watching your favorite shows on the 27-inch TV. A large walk-in front wardrobe and underbed storage offer more room to keep your camping necessities, and a fully stocked gallery allows you to cook up a storm. Heartland RV.
