01 What makes it unique
The 3520 takes the 3500’s layout and rotates the entire living room 90 degrees. Where the 3500 puts a four-seat party sofa on the campside wall, the 3520 splits that seating into two double recliners with heat and massage facing a televator TV and an electric fireplace — a conversation-and-TV arrangement built for full-time living rather than a weekend party. Dual opposing slides are floor-flush, so there is no slide step to cross, and the chef gets the same waterfall island that converts to a peninsula with a spice rack and a pull-down utensil tray. The 11-foot garage carries a max-space half bath with fold-away walls plus a loft, and a washer/dryer-prep option deletes the half bath for loading length.
It tows like the 3500. RVUSA lists a published 22,000-pound GVWR against a 17,496-pound dry weight, leaving a 4,504-pound payload and a 3,150-pound dry pin. The full Model G running gear is standard — the single continuous I-beam chassis on three 8,000-pound axles, the 30,000-pound Gen-Y pin box, SumoSprings and disc brakes — and the front private bedroom carries a king bed slide-out, under-bed drawers with motion lights, a dresser with hidden storage and a walk-in closet with cordless-vacuum prep.
At an MSRP of $210,828 it sits just above the 3500. For a full-timing couple who wants the same chassis and garage but a living room arranged for watching and talking rather than a big party sofa — with floor-flush slides and a televator — the 3520 is the layout to choose.

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 3520 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
Living room rotated 90°
Two double recliners with heat and massage facing a televator and fireplace — conversation-and-TV seating instead of a party sofa.
Floor-flush slides
Both opposing slides are floor-flush — no raised slide floor to step over, a full-timer comfort detail.
Flex garage, half bath optional
An 11-foot garage with a max-space half bath that folds away — or a washer/dryer-prep option that deletes the half bath for loading length.
Biggest black tank here
An 85-gallon black tank — the largest among the shorter Model G plans, for longer stays.
05 How it compares
The mechanically near-identical sibling with a classic four-seat sofa and mid-coach kitchen — lower price, more payload.
A 16-foot “Garage-Mahal” with loft and half bath — far more garage if your toys need the room.
Brinkley’s mid-size rear-patio coach — much lighter and shorter if you want a patio without a full garage.
