2026 Passport SL2080MK

The Passport SL 2080MK is a front private custom king bedroom, a rear bath, a single slide and an outdoor kitchen — a 24-foot travel trailer aimed at couples who want a king bed and an outside kitchen at the lightest possible weight. It is the only profiled Passport SL with a 66-by-80 custom king, and it pairs that with an 18,000-BTU Chill Cube air conditioner and HyperCore laminated walls despite the sub-5,300-lb shipping weight.

It carries Keystone's Passport SL build — laminated, gel-coated filon sidewalls, a fully walkable roof, a one-piece polypropylene underbelly, a high-impact thermoset-resin front cap and Dexter torsion rubber-ride axles on Tamarack tires, on tandem axles. At 5,260 pounds dry against a 7,485-pound GVWR it leaves 2,225 pounds of cargo capacity, and the dry tongue weight is 570 pounds. A 10 cu ft refrigerator and 18K BTU air conditioning round out the equipment.

A figure worth stating plainly: Shipping weight (5,260 lb) and the 7,485-lb GVWR are both Keystone-published on the factory page (GVWR = shipping + the 2,225-lb carrying capacity). New-for-2026 floorplan; confirm the loaded weight against the unit's sticker. As with every lightweight trailer, the published tongue weight is a pre-production dry estimate — once water, gear and passengers are aboard, real loaded tongue weight runs higher and lands on the tow vehicle's payload, so weigh the loaded trailer and match it to your truck honestly before relying on the brochure number. For couples who want a king bed and an outside kitchen at the lightest possible weight, the 2080MK is a well-targeted pick within the Keystone value stack.

Keystone's Passport spans two builds under one nameplate: the ultra-lite Passport SL (Super Lite) line for SUVs and half-tons, and the premium Passport line with a painted fiberglass front cap, vaulted ceilings and a 15K air conditioner. The plan on this page is highlighted; each profiled plan links to its own page. The full Passport catalog runs to dozens of floorplans across both builds — the highest-demand layouts are detailed here and the rest are catalogued on the Passport hub.

This floorplan carries its water comfortably. A full 54-gallon fresh tank is roughly 20% of the 2,225-pound cargo capacity, leaving the 2080MK with a usable gear budget even when you tow full.

The published dry tongue weight of 570 pounds is 11% of the 5,260-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 7,485-pound GVWR the 2080MK is towing 2,225 pounds more than its 5,260-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 38 grey and 38 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by GVWR, the 2080MK sits 2 of 9 in the Passport line: 7,485 pounds against a line that runs from 7,179 to 10,571 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: Passport 2450RK is 306 pounds lighter at 7,179 lb GVWR; and Passport 229BH is 115 pounds heavier at 7,600 lb GVWR.

Against the 2080MK: the Westbrook 25BHCC is 5 lb heavier and 4 ft longer; the Transcend Xplor 25MLX is 10 lb heavier and 5 ft longer and sleeps 2 more; the Surveyor Legend 202RBLE is 12 lb heavier. 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 Passport floorplans profiled here run 5,260 to 8,505 pounds dry and 25 to 38 feet of exterior length across 9 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 Passport line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 16 of them for the 2080MK. 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: exterior width, interior height, 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 (88%) 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.
