01 What makes it unique
The Reflection 320MKS centers the kitchen in the middle of the coach and adds an outside kitchen and a built-in desk — a layout for couples who cook seriously and work from the road. The mid galley separates the living and sleeping ends, the outdoor kitchen moves cooking into the open, and the desk gives a dedicated work surface. The Reflection residential build is fully present: gel-coat fiberglass sidewalls, laminated aluminum framing, a one-piece TPO roof and a 16 cubic-foot 12-volt refrigerator.
It rides on a tandem axle with MORryde rubberized suspension and Goodyear Endurance tires, with a 13,995-pound GVWR on an 11,100-pound dry weight — leaving nearly 2,900 pounds of payload — and a 2,200-pound dry pin weight that wants a three-quarter-ton. It carries the largest gray tank in the line at 94 gallons alongside a 74-gallon fresh, supporting long off-hookup stays, and is framed for a second air conditioner.
It sleeps four in a work-and-cook couples’ layout, at an MSRP near $98,000. For buyers who want a serious kitchen, an outdoor galley and a workspace in a full-size fifth wheel — with the tank capacity for extended boondocking — the mid-kitchen 320MKS is the most kitchen-focused full-size Reflection.

03 The Reflection floorplan family
Grand Design's Reflection is the brand's premium-mainstream towable family, and it spans four sub-lines across both tow types. The full-size Reflection fifth wheel is the heart of the range — a residential half-ton-to-three-quarter-ton coach with a 16 cubic-foot refrigerator and laminated aluminum construction. The Reflection travel trailer (the "...TS" plans) brings that same finish to a genuine bumper-pull, for buyers who want Reflection quality without an in-bed hitch. The Reflection 150 Series is the lightest fifth wheel — CURT Touring Coil suspension, standard solar and a 90-degree turning pin box for short-bed half-tons — and the Reflection 100 Series is the accessible short-bed fifth-wheel entry. The 320MKS on this page is highlighted; each other profiled plan links to its own page. The full Reflection catalogue runs to dozens of floorplans across all four; the highest-demand layouts are detailed here and the rest are catalogued on the line hub.

The full-size Reflection fifth wheel is the volume heart of the line, sitting below the luxury Solitude and new Influence fifth wheels and above the lighter 150 and 100 Series. Pin weights are factory dry figures and climb with cargo — even a half-ton-rated coach needs its loaded pin checked against the truck's payload and rear-axle rating. Additional Reflection fifth-wheel floorplans are catalogued on the line hub.
04 What owners & reviewers report
Mid-kitchen + outside kitchen
A center galley plus an outdoor kitchen makes it the most cooking-focused full-size Reflection.
Largest gray tank in the line
94 gallons of gray alongside a 74-gallon fresh stretches long off-hookup stays.
Built-in desk
A dedicated work surface suits couples working from the road — uncommon in this class.
Wants a 3/4-ton
A 2,200-lb dry pin and 13,995-lb GVWR are beyond half-ton territory — weigh loaded and check truck ratings.
05 How it compares
The rear-living layout in the same class — living-room emphasis instead of a center kitchen.
A quad-slide bunkhouse — the family layout above this couples’ kitchen coach.
Grand Design’s luxury extended-stay fifth wheel one tier up — more space and a higher price.
