    • The refrigerator is located on the off-door side, along with a hide-a-leaf dinette with buffet as well as 2-fixed & 2 folding chairs.
    • Mid-coach, the 4589 offers a work desk and chair with overhead cabinet and large window providing natural light.  There are plenty of outlets, a drawer and roomy storage for anyone wanting to work, study or operate their business from the comfort of their Mountain Aire.
    • A large and spacious walk through bathroom is located rear of the kitchen and study and forward of the master bedroom.  This bath area provides amenities such as a 50” X 34” shower, a dual sink vanity, and enclosed stool room as well as linen storage.

FLOORPLANS (continued)

2022 Mountain Aire 4589 (continued):  

    • The rear master bedroom offers a 72” X 80” king size bed, as well as a large wardrobe with sliding doors that spans the rear wall of the room and houses the standard washer and dryer.


  • Blu-Ray players have been eliminated for the 2022 model year.  With streaming increasingly being used for entertainment, Blu-Ray technology is becoming more and more obsolete.  AV provisions remain, however, in the event a customer elects to add their own Blu-Ray player after purchase.
  • The standard hydronic heater on the Oasis system changes to a dual loop Chinook system.
  • The 2022 Mountain Aire features a new 10” Xite dash monitor system with NavnGo navigation system.  The NavnGo system replaces Rand McNally navigation as Rand McNally no longer supports RV applications.  The new NavnGo system does have vehicle dimension capabilities as it uses a dual CAN controller and Android based operating system with over the air updates and uses no SIM card.


  • The height of the bottom of the kitchen overhead cabinets has been raised to a standard height of 18.5” above the kitchen countertop.
  • The Carmel Glazed Maple finish offered in 2021 has been replaced with Toffee Glazed Maple.
  • Rear wardrobes will feature cedar lining only on the rear wall.
  • The pull out drawers in kitchen overhead cabinets are wider in the 2022 Mountain Aire in order to better utilize all the available space.

  • The Cummins X-12 engine featured in all 2022 Mountain Aire models has had some minor modifications made so as to meet the EPA’s new emission standards for 2022.


  • The 2022 Mountain Aire features a new app to allow remote control of numerous features from a personal device.  This is a local application that operates off the coach’s Wi-Fi system, so the user must be within the range of the motor home’s wireless system.  This application is available on Apple and Android devices.  This new app allows control of many of the same functions available on the internal Silverleaf panel.  This includes tank levels, climate control, AC and DC power system status, water pump, auto tank fill, entry and baggage door locks, interior main group lighting controls including dimming, security lights, and group window shade controls.
  • LED strip lighting has been added inside all wardrobes with automatic switches.  This includes shirt wardrobes.
  • For 2022, the 110 volt receptacles in the bedroom have been relocated to inside the night stands just like they are in the King Aire.  This allows for cords to pass over the top of the style so that appliances can be plugged in without having to open the cabinet door.
  • An “all lights off” function has been added to the KIB switch panel in the bedroom.  This new feature allows for the lights throughout the coach to be turned off from the bed.  These lights would have to be turned on individually once they are all turned off using this new feature.  
  • KIB switch panels will now feature LCD touch screens.
  • The tank monitor will have a new touch screen display.
  • The desk area on the new 4589 floor plan will have 2 lights in the ceiling as well as one under the overhead cabinet. There are also two additional electrical outlets, one containing a USB port.

  • Metal trim has been added to the backsplash located in the main bath area.
