2026 Brinkley Model Z3110

The 3110 is Brinkley’s family bunkhouse on the same easy-towing 7,000-pound chassis as the lighter couples plans. Its defining feature is a private rear bunkhouse with 54-by-74-inch bunks and its own rear pass-through storage compartment with camp-side access — a dedicated kids’ zone behind the living space. Up front, dual slides open a center-island kitchen and a living room with a large theater seat, two recliners and a 60-inch tri-fold sofa, a televator smart TV that rises above the fireplace, an island with dual pull-out trash and built-in pet bowls, a 16-cubic-foot refrigerator, a 30-inch residential microwave and an 84-inch pantry. A private front queen bedroom and full bath complete a plan rated to sleep up to eight.

It stays light for a triple-slide family coach. RVUSA lists a published 15,495-pound GVWR against a 12,379-pound dry weight, leaving a 3,116-pound payload and a 2,331-pound dry pin — figures a properly rated three-quarter-ton truck can carry. The full Brinkley build carries through on the monotube triple-powder-coated chassis with 7,000-pound tandem axles on 8,000-pound leaf springs, a CURT Touring Coil suspension with ABS, a Helux king pin and brass plumbing, with two air conditioners, a 16-cubic-foot 12-volt refrigerator, a 370-watt solar package and the class-leading 79.5-inch bed and bath ceiling height standard.

At an MSRP of $117,874 it sits in the heart of the line, with dealers commonly selling well under the placard. For a family that wants a real, private bunk room and a center-island kitchen in Brinkley’s luxury build — in a coach a three-quarter-ton truck can tow comfortably — the 3110 is the mid-size luxury bunkhouse.

The Brinkley Model Z is a mid-size luxury fifth wheel and one of the most talked-about new entrants in the segment. The line runs to twelve floorplans for 2026; the eight highest-demand layouts are profiled here in full, and the remaining four are catalogued on the line hub. The 3110 on this page is highlighted; each other profiled plan links to its own page.

This floorplan carries its water comfortably. A full 75-gallon fresh tank is roughly 20% of the 3,116-pound cargo capacity, leaving the 3110 with a usable gear budget even when you tow full.

The published dry pin weight of 2,331 pounds is 19% of this floorplan’s 12,379-pound dry weight. Fifth-wheel pin weight rides in the bed of the truck, so it comes off payload rather than off tow rating — and it rises with the trailer as you load it, not in proportion to what you put over the axles.

Nothing above changes the ceiling. Loaded to its 15,495-pound GVWR the 3110 is towing 3,116 pounds more than its 12,379-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 75 gallons of fresh against 90 grey and 45 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by GVWR, the 3110 sits 6 of 11 in the Model Z line: 15,495 pounds against a line that runs from 13,995 to 17,695 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: Model Z 3100 matches it exactly at 15,495 lb GVWR; and Model Z 3300 is 1,500 pounds heavier at 16,995 lb GVWR.

1 other Model Z plan shares this floorplan’s 15,495 lb GVWR, so the ranking above separates plans that tow to the same ceiling. On a shared chassis the figure that actually differs between them is cargo capacity and where the weight sits, not the rating.

Against the 3110: the Wildcat 37BEST is 3 lb heavier and 9 ft longer and sleeps 2 more; the Sandpiper 3710HBFB is 5 lb heavier and 8 ft longer and sleeps 1 fewer; the Sierra 3710HBFB is 5 lb heavier and 8 ft longer. 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 fifth wheels 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 Model Z floorplans profiled here run 10,691 to 14,859 pounds dry and 30 to 42 feet of exterior length across 11 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 Model Z line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 17 of them for the 3110. 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 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 (98%) 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.
