## Overview

The 3400KD sits on a Freightliner M2 112 Plus chassis with a Cummins L9 producing 450 horsepower and 1,250 lb-ft of torque — numbers that make 20,000-lb towing feel effortless, whether you're hauling a fifth wheel, toy hauler, or full-size boat. Up front, the cab-over bunk adds real sleeping space for adults, not just kids, which is rare in this segment. Back in the rear, the King bed anchors a private bedroom with a full bath, while the front living area keeps the social space separate from sleeping quarters. The optional Xplorer Package — dual lithium batteries, 1,000W solar, and insulated utility bay — pushes this well into off-grid capable territory for those who want the power and the freedom to go with it.
