2026 Catalina 231MKS

The Catalina Summit Series 8 231MKS is the value tier’s rear-living couples’ coach — a front private bedroom with a walk-around queen, a walk-through bath linking it to the living area, and a rear U-shaped dinette under big windows with power theater seating built into the slide. The galley sits mid-coach with a GE three-burner range, a stainless microwave and a deep farm-style sink, and a pass-through storage bay runs under the bed. Nominal sleeping is four — the U-dinette converts for an occasional guest — making this a couples-first layout rather than a family bunkhouse.

At 5,706 pounds unloaded and 28 feet 2 inches, the 231MKS is an easy half-ton or capable-SUV tow with a 1,500-pound cargo capacity. As a Summit Series 8 it carries the line’s standard full-12-volt residential equipment — a GE 10.7-cubic-foot 12V refrigerator, a 60,000-BTU tankless water heater and a 13,500-BTU ducted heat-pump air conditioner — plus JBL Aura audio and a 600-watt solar prep. Unusual for a Summit plan, it gets the 35,000-BTU furnace with residential in-floor ducted heat (the no-slide 211BH/221EPIC/261BH plans drop to a smaller furnace), and power theater seating is standard on this layout. An 18-foot power awning throws shade over the rear-living end.

Construction is the line’s metal-sided value build — a Norco powder-coated steel I-beam frame with full-length outriggers, a Platinum .024-inch aluminum exterior with a smooth radius front, a seamless Alpha roof membrane and a 5/8-inch StableDeck floor. Being a Summit plan it uses Thermofoil counters rather than the Legacy tier’s solid surface and skips the outside camp kitchen. For a couple who wants a true rear-living lounge and a private front bedroom at the value tier’s lightest practical weight, the 231MKS is the rear-living pick of the Summit line.

Coachmen's Catalina is one of the highest-volume value travel-trailer nameplates in North America, spanning several sub-lines: the lighter Summit Series 7, the mainstream Summit Series 8, the full-feature Legacy Edition, the Trail Blazer toy haulers and the Destination park trailers. The 231MKS on this page is highlighted; the other profiled plans link to their own pages. Profiled here are breadth-spanning Summit 8 and Legacy Edition floorplans — the rest of the roster is catalogued on the line hub and profiled in demand order.

This floorplan carries its water comfortably. A full 38-gallon fresh tank is roughly 21% of the 1,500-pound cargo capacity, leaving the 231MKS with a usable gear budget even when you tow full.

The published dry tongue weight of 730 pounds is 13% of the 5,706-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 7,206-pound GVWR the 231MKS is towing 1,500 pounds more than its 5,706-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 38 gallons of fresh against 44 grey and 28 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by GVWR, the 231MKS sits 4 of 20 in the Coachmen Catalina line: 7,206 pounds against a line that runs from 6,518 to 11,458 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: Coachmen Catalina 221EPIC is 396 pounds lighter at 6,810 lb GVWR; and Coachmen Catalina 261BHS is 392 pounds heavier at 7,598 lb GVWR.

Against the 231MKS: the Bullet 2240RK is 6 lb lighter and 1 ft shorter and sleeps 1 more; the Jay Feather 26BHSL is 6 lb lighter and 2 ft longer and sleeps 6 more; the Jay Flight 245BHS is 6 lb lighter and sleeps 4 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 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 Coachmen Catalina floorplans profiled here run 4,647 to 9,130 pounds dry and 26 to 38 feet of exterior length across 20 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 Coachmen Catalina line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 16 of them for the 231MKS. 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, tire specification. 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 (93%) 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.

Values on this page carrying an asterisk were derived by arithmetic from published figures, or come from a single source, rather than being printed directly by the manufacturer. The flag travels with the number into the downloadable spec sheet.

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