## Overview

The 3525SOX earns its following with a layout that punches above its class — a dedicated office space sets it apart from most fifth wheels in this range, and the galley delivers with pendant lighting, a giant dual-bowl stainless sink, flush floor slides, and a pull-down faucet. Back in the living area, theater seats with LED lighting and massage make the evening routine genuinely comfortable. Forest River leans hard into residential quality throughout: Baltic birch drawer boxes, solid wood cabinet accents with backlit crown molding, and a built-in home vacuum signal a brand that's been refining the Cardinal line for over two decades. The bedroom is well-appointed with a Denver mattress, a full-height hanging wardrobe, and nightstands with USB ports, while optional upgrades like the Whirlpool washer/dryer, Winegard 4G LTE extender, and six-point hydraulic leveling system let you tailor it for full-time living or extended-season camping.
