2026 Grand Design Reflection345RLTS

The Reflection 345RLTS is the longest and most residential travel trailer in the line — a near-39-foot rear-living coach with three slides, a large kitchen island, theater seating and a fireplace. It gives the kind of open living space usually associated with a fifth wheel while staying a conventional bumper-pull. The Reflection build is fully present: gel-coat fiberglass sidewalls, laminated aluminum framing, a one-piece TPO roof, a 7-foot ceiling and a 16 cubic-foot 12-volt refrigerator.

It rides on a tandem axle with MORryde rubberized suspension and Goodyear Endurance tires, fitted with dual air conditioning across 28,500 BTU. An 11,995-pound GVWR on a 10,275-pound dry weight leaves 1,720 pounds of payload, with a 1,400-pound dry tongue weight — the heaviest of the Reflection travel trailers — that wants a well-equipped three-quarter-ton. A 54-gallon fresh tank supports long stays.

It sleeps six in a layout built around living space rather than berth count, at an MSRP near $89,300. For buyers who want fifth-wheel-like rear living and dual-A/C comfort in the largest bumper-pull Reflection offers, the tri-slide 345RLTS is the top of the travel-trailer range.

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 345RLTS 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.

This floorplan carries its water comfortably. A full 54-gallon fresh tank is roughly 26% of the 1,720-pound cargo capacity, leaving the 345RLTS with a usable gear budget even when you tow full.

The published dry tongue weight of 1,400 pounds is 14% of the 10,275-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 11,995-pound GVWR the 345RLTS is towing 1,720 pounds more than its 10,275-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 78 grey and 39 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by GVWR, the 345RLTS sits 16 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 303RLS matches it exactly at 11,995 lb GVWR; and Reflection 311BHS is 2,000 pounds heavier at 13,995 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 345RLTS: the Eagle 312BHOK sleeps 2 more; the Jay Flight 401FLTS is 5 lb heavier and 2 ft longer and sleeps 2 fewer; the Puma Vista 39DBT is 5 lb heavier and 4 ft longer. 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 345RLTS. 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.
