## Overview

Powering this rig is a Cummins ISB 6.7L diesel making 360 HP and 800 ft-lbs of torque on a Freightliner S2RV Plus chassis—a drivetrain combination that earns consistent praise from owners for its confidence on the highway and 12,000-lb tow capacity. Inside, the bath-and-a-half layout with rear bath keeps things civilized when multiple people need to get ready at once, and the cabover bunk adds sleeping flexibility without eating into the main living space. The exterior entertainment center with JBL speakers and a swivel-mounted LED Smart TV means the fun doesn't stop when you unhitch, and an Onan 8,000W quiet diesel generator with auto-start keeps everything running off-grid. Luxury touches like the Firefly total coach control system, Alcoa aluminum wheels, full-body Sikkens paint, and premium solar and battery setup place this squarely in the high-end Class C category.
