2026 Grand Design Reflection303RLS

The Reflection 303RLS is the floorplan that built the line’s reputation — a rear-living fifth wheel with three slides, a rear tri-fold sofa and theater seating facing an entertainment center and fireplace, a kitchen island, and a private front bedroom up in the raised nose. It is a genuinely spacious couples’ coach that many owners tow with a three-quarter-ton or a well-equipped half-ton. The Reflection build is residential: gel-coat fiberglass sidewalls over 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 an 11,995-pound GVWR on a 10,100-pound dry weight — leaving 1,895 pounds of payload — and a 1,980-pound dry pin weight. A large 74-gallon fresh tank, an 87-gallon gray and a 16 cubic-foot refrigerator support extended and full-time stays, and the coach is wired and framed for a second air conditioner.

It sleeps four in a couples-first layout, at an MSRP near $87,000 — the accessible entry to the full-size Reflection fifth wheels. For buyers stepping up from a travel trailer to a fifth wheel who want residential rear living without a heavy-duty dually, the tri-slide 303RLS is the line’s most popular floorplan for good reason.

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 303RLS 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.

Fresh water is the single biggest line in this floorplan’s load plan. A full 74-gallon tank is about 33% of the 1,895-pound cargo capacity — enough that whether you tow with water aboard is a real decision on the 303RLS rather than a detail.

The published dry pin weight of 1,980 pounds is 20% of this floorplan’s 10,100-pound dry weight. Fifth-wheel pin weight rides in the bed of the truck, so it comes off payload rather than off tow rating — and it rises with the trailer as you load it, not in proportion to what you put over the axles.

Nothing above changes the ceiling. Loaded to its 11,995-pound GVWR the 303RLS is towing 1,895 pounds more than its 10,100-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 74 gallons of fresh against 87 grey and 47 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by GVWR, the 303RLS sits 15 of 23 in the Reflection line: 11,995 pounds against a line that runs from 9,995 to 14,995 pounds. That position is the useful thing to know, because the plans immediately either side of it are the real alternatives.

Either side of it in the same line: Reflection 32BH matches it exactly at 11,995 lb GVWR; and Reflection 345RLTS matches it exactly at 11,995 lb GVWR.

2 other Reflection plans share this floorplan’s 11,995 lb GVWR, so the ranking above separates plans that tow to the same ceiling. On a shared chassis the figure that actually differs between them is cargo capacity and where the weight sits, not the rating.

Against the 303RLS: the Arctic Wolf 289PANO is 25 lb lighter and 2 ft longer; the Cardinal 32CHILL is 193 lb heavier and 2 ft longer; the Eagle 31QBH is 295 lb lighter and sleeps 3 more. Those are differences in the published numbers only — what they cost, how they are built and how they live are separate questions each of those pages answers on its own terms.

Those are the nearest fifth wheels from other lines by weight — one per line, picked by proximity on that figure and nothing else. They are listed so the same tow vehicle can be checked against real alternatives, not because they are equivalent inside; layout, build and price diverge sharply across that group.

For scale, the Reflection floorplans profiled here run 7,000 to 12,900 pounds dry and 27 to 41 feet of exterior length across 23 plans. Where a floorplan falls in that spread usually says more about which vehicle can tow it, and which site it fits, than the layout name does.

Every profiled floorplan in this line, with the full weight table, is on the Reflection line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 16 of them for the 303RLS. The rest are not shown, because the alternative is reading a figure across from a sibling floorplan or from what the segment usually does — and a number nobody published is worth less than an admitted gap.

Not published for this floorplan: interior height, awning, tire size (a tire description is published, a size is not). If you find one of these in a manufacturer document for this plan, it belongs on this page.

The completeness figure at the foot of this page (100%) measures the same thing on the full field set: it is a measurement of how much this floorplan’s manufacturer publishes, not of how much research went into the page.

How every figure here was sourced and checked is set out on the methodology page.
