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.
