Used 2020 Heartland Milestone 370FLMB — Large-Scale Comfort Meets Family & Group Flexibility

The 2020 Milestone 370FLMB is a full-size fifth wheel built to deliver space, comfort, and flexibility for families or groups who want more than a basic camper. As a used model, it provides a strong value: plenty of room, smart layout, and living features — without the full-new price tag. If you want to travel with family or friends, bring guests, or even accommodate extended stays, this model offers a full-featured home-on-wheels setup.


What the 370FLMB Offers

Flexible Layout with Multiple Living Zones

  • A front living area with opposing sofas and theater-style seating gives a real “living-room” feel for relaxing, socializing, or watching TV. 

  • A separate kitchen and dining area with dual slides — ideal for cooking meals, dining comfortably, or organizing gear without feeling cramped. 

  • A private master bedroom with a king bed for restful sleep — great for couples or whoever needs privacy at night. 

Extra Sleeping & Guest Spaces

  • Mid-section bunkhouse plus a loft provide extra sleeping or storage space, making it suitable for kids, guests, or extra passengers.

  • The living area sofas offer additional sleeping flexibility when needed — useful for guests or larger groups traveling together.

Comfort and Convenience Features

  • Solid-surface kitchen countertops, hardwood-style cabinetry and drawers, a residential-style refrigerator, and practical living amenities deliver a “home away from home” experience. 

  • Built-in features like tinted safety-glass windows, exterior graphics, and thoughtful floorplan design offer durability, good ventilation/light, and a comfortable travel lifestyle. 

  • Layout and build work well for seasonal trips, long weekend getaways, or extended vacations — the 370FLMB blends practicality with roomy design so you don’t feel cramped even on longer stays.

Strong Value as a Used Fifth Wheel
Because this is a used 2020 unit, you’re likely getting a lot of the comfort, layout, and versatility of a large fifth wheel — but at a more accessible price compared with new units. For many buyers, that makes it a smart balance of size, amenities, and cost.


Who the 2020 Milestone 370FLMB Is Great For

  • Families or groups needing multiple sleeping areas and flexible living/sleeping setups.

  • Travelers who want the comforts of home — kitchen, living space, private bedroom, good storage — without stepping up to a motorhome.

  • Vacations, seasonal stays, long road trips, or repeated camping with friends/guests.

  • Buyers looking for value: a well-equipped fifth wheel with a proven layout and comfort, but at used-price value rather than new-unit cost.


Why Buying a 2020 Milestone 370FLMB from a Capital RV in Minot Makes Sense

Trusted Dealer Support & Realistic Guidance
A reputable dealer who knows this model and the local travel conditions can help you get the right unit, understand what to expect long-term, and match the RV to your real needs.

Post-Sale Support & Maintenance Options
Used doesn’t have to mean “you’re on your own.” A good dealer will offer maintenance support, advice, and resources — helping the RV stay reliable for many seasons ahead.

Balanced Price vs. Features — Strong Value
Because this is a used unit, you often get a lot of the benefits — space, amenities, flexibility — at a price that avoids the steep depreciation of a new RV. It’s a practical way to enjoy fifth-wheel living without overspending.

Flexibility for Many Lifestyles
Whether you’re planning family trips, seasonal travel, guest stays, or occasional getaways, this RV fits a broad range of uses. A good dealer will help ensure you get the configuration that matches how you travel.

 

Less Pressure, More Reality in Buying
A dealer you trust will focus on what works for you — not upsells or extras. The buying process stays straightforward and transparent.

What Our Customers Are Saying

Fantastic service and support!

Fantastic service and support. Jim and Mike know RVs and even more important know the industry and all the conditions that are affecting RV sales. In addition, RV Kountry went above any beyond when it comes to the sale of my coach. They coordinated battery replacements and other repairs. I would highly recommend RV Kountry. Thanks for all your help. - Greg
