Name: 2026 Grand Design Reflection 345RLTS
Brand: Reflection

01 What makes it unique

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.

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 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.

The Reflection travel trailer brings the line's residential finish to a bumper-pull, for buyers who want Reflection quality without an in-bed hitch. It sits above Grand Design's Imagine and Transcend trailers in finish and price. Tongue weights are factory dry figures and climb with cargo — weigh the loaded trailer and confirm against your vehicle's door-jamb placard. Additional Reflection travel-trailer floorplans are catalogued on the line hub.

04 What owners & reviewers report

Fifth-wheel space, trailer towing

Three slides and a rear living room give residential room in a bumper-pull — no in-bed hitch required.

Dual A/C + island kitchen

28,500 BTU of cooling and a large kitchen island make it a genuine long-stay couples’ coach.

Heaviest tongue in the TT line

A 1,400-lb dry tongue and 10,275-lb dry weight want a well-equipped 3/4-ton — check payload carefully.

05 How it compares

↓ Step down

Reflection 317RSTS

A shorter rear-living trailer — lighter tongue and easier to tow if the extra length isn’t needed.

↔ Cross-shop

Reflection 303RLS

The full-size fifth-wheel take on rear living — a more planted tow with a raised front bedroom.
