You'll be able to see the country in full luxury with this Milestone fifth wheel! There is a private bedroom in the back with a king-size bed where you can sleep comfortably each evening. The middle bunkhouse offers a comfortable sleeping area for two other tired travelers, and there is even a loft above the bunkhouse too. The separate living room replicates your living room back at home with its opposing sofas, theater seating, and Smart TV with a JBL sound system. You'll be very happy to find a fully functional kitchen that offers all of the essentials, like a three-burner cooktop, 21" large RV oven, 30" over-the-range microwave, and 10.7-cubic foot refrigerator. 


The Heartland Milestone is a full-profile luxury fifth wheel that is ready to help you make the most of your adventures! You will find an anti-chucking Rota-flex 2" receiver hitch to help you tow like a pro, and the Sol-380 with two 190 watt solar panels will let you go off-grid when the adventure calls for it. The upgraded MORryde solid step with quick-adjust system will help you enter your unit with ease, and auto-leveling comes standard to help you keep your unit secure while camping. The interior kitchen has some great features, like anti-microbial solid-surface countertops and a refrigerator with a wine cooler, and there is Wi-Fi prep with wireless charging ports throughout each unit.
