Heartland Big Country fifth wheel 3900MO highlights:


This fifth wheel is big enough for the whole family to join in on the fun at the campground! There is not only a front private bedroom with a king bed slide and a closet prepped to add a washer and dryer, but also a second bedroom with a loft above a sofa, a desk, and a wardrobe. Meal prepping is made easy with a kitchen island with dishwasher prep, and a four burner cooktop so you can cook more food at one time. There is a floating dinette table with four chairs to enjoy your meals at or play a game of cards, and the dual recliner love seat is directly across from the 55" smart TV and fireplace with hidden storage. And if you have any more guests sleep over, they can crash on the rear tri-fold sofa!


Each Big Country fifth wheel by Heartland is constructed with double layer Azdel composite panels, a 12" powder coated steel I-beam frame, and TPO roofing material for added durability. You will have smooth trips to the campground thanks to the upgraded Rota Flex pin box and MORryde 3000 suspension with leaf springs, a wet bold kit, and shock absorbers. The innovative storage design includes three points of access for easy loading and unloading, plus there is entertainment prep outside and insulated slam style cargo doors with magnetic hold backs for convenience. The interior is packed with luxury touches, like the stained hardwood cabinetry, stainless steel appliances, master bedroom storage, a designer island, and the list goes on!
