2026 Grand Design Reflection312BHTS

The Reflection 312BHTS is the most in-demand bunkhouse in the Reflection travel-trailer line and the one built for families who want residential finish at family capacity. Three slides and a near-37-foot length make room for a private front master with a sliding door, a rear bunkhouse with multiple bunks and storage, and an open center living area with a U-shaped dinette, theater seating and a fireplace. An outside kitchen moves cooking into the open, and a 7-foot interior ceiling keeps it airy.

It rides on a tandem axle with MORryde rubberized suspension and Goodyear Endurance tires, with an 11,295-pound GVWR on a 9,800-pound dry weight — leaving 1,495 pounds of payload — and a 1,190-pound dry tongue weight that wants a well-equipped half-ton or a three-quarter-ton. A 54-gallon fresh tank, an 86-gallon gray and a 16 cubic-foot 12-volt refrigerator carry a family through a long stay.

It sleeps six in the Reflection residential build, at an MSRP near $89,600 — the top of the travel-trailer range in both finish and price. For families who want Reflection quality and an outdoor kitchen but prefer a conventional trailer to a fifth wheel, the triple-slide 312BHTS is the family flagship of the line.

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 312BHTS 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 54-gallon tank is about 30% of the 1,495-pound cargo capacity — enough that whether you tow with water aboard is a real decision on the 312BHTS rather than a detail.

The published dry tongue weight of 1,190 pounds is 12% of the 9,800-pound dry weight, which sits inside the 10–15% band usually quoted for stable towing. It is still a dry figure: loading the front pass-through and the fresh tank both push it up.

Nothing above changes the ceiling. Loaded to its 11,295-pound GVWR the 312BHTS is towing 1,495 pounds more than its 9,800-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 54 gallons of fresh against 86 grey and 43 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by GVWR, the 312BHTS sits 12 of 23 in the Reflection line: 11,295 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 322FKTS is 300 pounds lighter at 10,995 lb GVWR; and Reflection 342BHTS matches it exactly at 11,295 lb GVWR.

1 other Reflection plan shares this floorplan’s 11,295 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 312BHTS: the Puma 32BHFS is 13 lb heavier and 1 ft longer and sleeps 5 more; the Longitude 310RL is 15 lb lighter and 2 ft shorter; the Cherokee Timberwolf 20OG is 20 lb lighter and 2 ft shorter. 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 travel trailers 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 17 of them for the 312BHTS. 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: 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.
