2026 Keystone Montana3532SP

The 3532SP is the line’s side-patio plan — the "SP" is a fold-down deck that swings out from the roadside wall to add an elevated private patio off the living area, a feature no other Montana luxury floorplan offers. Inside it is a king-bed couples’ layout with a pull-down storage pantry, an L-shaped hide-a-bed sofa and powered theater seating across a fireplace, and a private front bedroom.

It rides on the full Montana luxury build and ships with the triple-15,000-BTU CX3 air-conditioning package and a 20-cubic-foot 12-volt refrigerator among its highlighted features. The 14,405-pound dry weight and 2,730-pound dry pin place it mid-pack on weight; the GVWR and payload shown are flagged — the 2026 structured payload was not separately published, so the figures carry forward the plan’s 16,500-pound rating pending plan-specific confirmation.

At an MSRP near $125,878 it slots between the rear-living couples’ plans and the larger four-slide coaches. It is the Montana for a buyer who wants an outdoor living space built into the coach — a patio plan in a class that almost never offers one.

Montana is Keystone's flagship luxury fifth wheel and the best-selling luxury fifth wheel in North America. The line runs to fifteen floorplans for 2026; the six highest-demand layouts are profiled here in full, and the rest — along with the lighter, lower-profile Montana High Country sub-line — are catalogued on the line hub. The 3532SP on this page is highlighted; each other profiled plan links to its own page.
