New 2026 Outdoors RV Trail Series MTN TRX Titanium Series 29TRX Toy Hauler Fifth Wheel

Why We Chose This Trail Series MTN TRX 29TRX
We selected this specific model because it offers the ultimate combination of high-capacity cargo utility and premium 4-season residential luxury in a rugged fifth-wheel platform. Built by Outdoors RV right here in the Pacific Northwest, the Trail Series 29TRX is designed to carry your side-by-sides, ATVs, or mountain gear deep into unpaved territory without sacrificing comfort. The heart of this coach is an expansive 13' 4" cargo garage area featuring an electric drop-down loft queen bed and dual opposing leather rollover sofas with a central table that converts into a massive secondary dining or sleeping layout. The rear ramp door lowers seamlessly to create an incredible outdoor patio railing setup with built-in steps, perfect for open-air relaxation. Up front, a private master suite offers a peaceful retreat with a walk-around queen bed and direct access to a spacious side-aisle bathroom with a glass neo-angled shower. The main living space boasts dual luxury recliners perfectly positioned across from an entertainment center with a 32" swing-out TV, while the gourmet kitchen features premium LG solid-surface countertops, a kitchen pantry, and a smart off-grid 12V refrigerator.
