Description
Dutchmen Yukon fifth wheel 399ML highlights:
- Triple Slides
- 18 Cu. Ft. Refrigerator
- Free-Standing Dinette
- Fireplace
- Shower with a Seat
- Pull-Out Laundry Hamper
The 399ML is geared toward “residential-style living” on the road. Some of its notable interior/lifestyle features:
-
Rear kitchen layout: The kitchen is located at rear — often considered a premium layout for convenience.
-
Large counter and storage space: The trailer boasts “largest countertop space in the industry” (by its manufacturer’s claim), deep cabinets, plus a full-size residential-style fridge (often 18 cu ft, French door type) for food storage.
-
Cooking & appliances: Includes a 4-burner cooktop with oven, a full-size microwave, and a stainless-steel (or similar) dual-bowl sink with high-rise faucet.
-
Living area comforts:
-
Electric-powered theatre seating or recliner sofas + a sofa bed/tri-fold sofa depending on configuration.
-
Fireplace(s) — at least one is standard in living area; often also a second in bedroom depending on layout.
-
Large panoramic/tinted windows for natural light and outside views.
-
Vinyl flooring throughout — easier to clean and maintain compared to carpet.
-
-
Master bedroom: Front bedroom with a slide-out king bed, with large wardrobe/closet space and storage drawers.
-
Bathroom: Large/better-than-average bath configuration — walk-through design, shower (often with seat), dual sinks (in many layouts), and good storage/vanity space.
-
Convenience features: Washer/dryer prep (linen closet), pull-out laundry hamper, pull-out storage trays, USB charging stations by night stands, LED HD TVs (living area and bedroom), and high-rise kitchen faucet.
In short — the interior is set up to be as close to a residential home as you can get in a fifth-wheel, promoting comfort for longer stays or full-time use.
Construction, Exterior & Utility / Build Features
The 399ML doesn’t skimp on structural quality or external utilities, which supports both durability and comfort:
-
Wide-body construction: The unit uses a “100-inch wide-body” frame design, giving extra space between sidewalls — allowing deeper slideouts, deeper-storage cabinets, and more spacious interior walk-through.
-
Solid entry and suspension: Equipped with a sturdy entry step system (MorRyde “Step Above”), plus a “MorRyde CRE 3000” suspension which helps with smoother towing and less stress on the frame.
-
Two awnings / dual awnings: The exterior includes two power awnings (often with LED lighting strips) — useful for shade and outdoor living.
-
Insulation & All-Weather Package: The 399ML often comes with an “All Weather Package,” which includes extra insulation and 12V tank pads — helpful for staying comfortable in varied climates.
-
Storage & utility features: Dual pass-through storage compartments (front & rear), pull-out storage trays for easy access, fully-walkable roof with ladder, roof-top solar prep (on many), backup camera prep, and 50-amp service for full hookups.
-
Water & power systems: Large fresh water capacity (162 gal) is excellent for extended stays; dual propane tanks; 50-amp electrical service; and standard utility connections.
