01 What makes it unique
The 3100 was the first floorplan Brinkley released, and it remains the line’s archetypal rear-living plan. Dual opposing slides open a bright, combined living and kitchen space: a 62-inch theater seat and a 72-inch tri-fold sofa run along the rear wall facing a televator and an electric fireplace, while a center kitchen island anchors the galley. The front holds a private bedroom with a king bed slide (queen optional). It is the layout most people picture when they think of the Model Z.
It stays in light-to-mid territory. RVUSA lists a published 15,495-pound GVWR against a 12,276-pound dry weight, leaving a 3,219-pound payload and a 2,298-pound dry pin — comfortable for a properly rated three-quarter-ton truck. The full Brinkley build carries through on the monotube triple-powder-coated chassis with 7,000-pound tandem axles, a Helux king pin and brass plumbing, with a 16-cubic-foot 12-volt refrigerator, 370-watt solar and the two-air-conditioner package standard.
At an MSRP of $121,244 it sits in the heart of the line, and it is one of the most cross-shopped Model Z floorplans. For a couple who wants the signature rear-living layout, a center island and a king bedroom in a 35-foot coach that still tows in the low-12,000-pound range, the 3100 is the Model Z that defined the brand.

The Brinkley Model Z is a mid-size luxury fifth wheel built by Brinkley RV, an independent manufacturer founded by RV-industry veterans. The full line runs to twelve floorplans for 2026; eight are profiled here and four more are catalogued above. Every plan rides on the same monotube triple-powder-coated chassis with 7,000-pound tandem axles on 8,000-pound leaf springs, a CURT Touring Coil suspension with ABS and a Helux king pin, and a fully enclosed, heated underbelly, and ships with a 370-watt roof solar package (740-watt ready) with a 50-amp MPPT controller, a 16-cubic-foot 12-volt refrigerator, brass plumbing fittings and a tankless on-demand water heater as standard — with a class-leading 79.5-inch bed and bath ceiling height. Body specifications (lengths, heights, payload, tanks, sleeping, slides and awnings) are RVUSA-verified against the 2026 structured spec records, each page fp-slug and title checked; dry weight, GVWR, payload and pin weight are published per plan, and each plan's dry weight plus payload equals its GVWR exactly. Real loaded pin weights run higher — always weigh the loaded coach and confirm against your truck's payload and rear-axle ratings.
04 What owners & reviewers report
The plan that launched Brinkley
The 3100 was the brand’s first floorplan — the rear-living, center-island layout most associated with the Model Z.
Dual opposing slides
Opposing slides open a bright combined living-and-kitchen space — a 62-inch theater seat and a 72-inch tri-fold sofa along the rear wall.
King front bedroom
A private front bedroom with a king bed slide (queen optional) — a full residential bed in a mid-size coach.
Mid-light weight
A 12,276-lb dry weight and 3,219-lb payload — a three-quarter-ton truck handles it comfortably.
05 How it compares
The shorter triple-slide rear-living plan — lighter and lower in price with a queen front master.
The rear-kitchen plan — a dual-entry center bath and the line’s biggest fresh tank at a longer length.
Keystone’s half-ton-and-up fifth-wheel line — a lighter, lower-cost mid cross-shop.
