A used 2005 Newmar Kountry Star 3910 is a luxury Class?A diesel motorhome built to deliver comfortable long-distance travel and live-aboard capability. Newmar’s Kountry Star lineup was designed with premium construction, smooth ride quality, and thoughtful residential-style interiors — making it a solid choice for families, couples, or full-time RVers looking for a well-appointed coach that holds up well over the years.


Overview & Key Attributes

Commercial-Grade Diesel Pusher

The 2005 Kountry Star 3910 typically shares its diesel pusher design with rugged, highway-proven components — including a strong chassis, low center of gravity, and often a Detroit Diesel Series?60 or similar heavy-duty engine paired with an Allison automatic transmission. This combination provides reliable power, greater torque for highway cruising, and strong towing capacity compared with many gas-powered Class?A models.

Spacious & Livable Interior

At around 39–40?feet long, the 3910 model offers a generous interior footprint with separate living, dining, sleeping, and bathroom areas. Newmar focused on a residential feel with features often including:

  • Large living area with opposing slides and comfortable seating
  • Well-appointed galley with ample counter space and residential appliances
  • Full bathroom with separate shower and plenty of storage
  • Private bedroom with a queen or king-size bed and wardrobe storage

Quality Construction

Newmar has a reputation for thoughtful construction techniques, often including:

  • Laminated sidewalls for insulated, solid structure
  • Quality cabinetry and trim work with attention to detail
  • Reliable plumbing and electrical systems designed for long-term use
