01 What makes it unique
The 4100 is the Model G aimed squarely at full-timers and big families. It is the longest plan in the profiled lineup at 45 feet 11 inches and sleeps up to eight, more than any other Model G here. The interior leans into living space: a large pantry, a double solid-surface waterfall island with generous countertop space, a kitchen island and a walk-in bedroom closet, plus space-maximizing fold-away rear-bath walls that recover loading length in the 12-foot-6 garage. The Brinkley G Dinesk convertible dining table/L-desk is standard on this plan, and a king bed slide-out anchors the front bedroom.
It is the heaviest of the seven. RVUSA lists a published 23,000-pound GVWR against an 18,600-pound dry weight, leaving a 4,400-pound payload and a 3,450-pound dry pin — a one-ton-and-up tow. The full Model G build is standard: the single continuous I-beam chassis on three 8,000-pound axles, the 30,000-pound Gen-Y pin box, SumoSprings, disc brakes, triple 13,500-BTU heat-pump air conditioners, 800-watt solar and the FlexPower 5500 generator. A bath-and-a-half serves the larger sleeping count.
At an MSRP of $235,372 it is the most expensive plan in the profiled lineup — the price of being the biggest, most sleeping-dense Model G. For a family or full-timing couple who wants the most interior living space, the most berths and a garage that doubles as a flex room, the 4100 is the top of the line.

03 The Model G floorplan family
The Brinkley Model G is the brand's luxury fifth-wheel toy-hauler line — a residential interior and an automotive exterior wrapped around a multi-purpose garage/flex space. The line runs to nine floorplans for 2026; the seven with published weights are profiled here in full, and the two front-office plans are catalogued on the line hub pending weight publication. The 4100 on this page is highlighted; each other profiled plan links to its own page.

The Brinkley Model G is the luxury fifth-wheel toy-hauler line from Brinkley RV, an independent manufacturer founded by RV-industry veterans. The full line runs to nine floorplans for 2026; seven are profiled here and two front-office plans are catalogued above pending weight publication. Every plan rides a single continuous I-beam chassis on three 8,000-pound axles with 8,000-pound leaf springs, a 30,000-pound Gen-Y Executive Torsion Flex pin box, SumoSprings and disc brakes as standard, and pairs a residential interior with an automotive exterior and a multi-purpose garage/flex space with a Zero-Gravity ramp door. Each ships with a 19-cubic-foot 12-volt refrigerator, triple GE low-profile 13,500-BTU heat-pump air conditioners, an 800-watt solar package, a FlexPower 5500 dual-fuel inverter generator and a Rockford Fosgate audio system. 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. A toy hauler's real loaded pin weight runs well above the base figure — always weigh the loaded coach and confirm against your truck's payload and rear-axle ratings.
04 What owners & reviewers report
Sleeps up to eight
The most berths of any profiled Model G — the family-and-full-timer plan in the lineup.
Walk-in bedroom closet
A true walk-in closet in the front bedroom — the residential storage detail full-timers ask for.
Double waterfall island
A double solid-surface waterfall island with generous counter space — the most kitchen prep room in the line.
Fold-away rear-bath walls
Space-maximizing fold-away rear-bath walls recover loading length in the 12-foot-6 garage.
05 How it compares
A 16-foot “Garage-Mahal” that trades some interior living for far more garage — lighter and lower-priced.
A 45-foot plan with two full baths instead of a bath-and-a-half — the two-bath alternative at the top of the line.
Brinkley’s mid-size flagship with a mid-coach bonus room — a much lighter, shorter coach if you do not need a true garage.
