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.
