## Overview

The 3700RB is built around a Freightliner M2 112 Plus chassis paired with a Cummins L9 turbodiesel pushing 450 horsepower and 1,250 lb-ft of torque. This is a Super C in every meaningful sense, with a 20,000-lb tow rating and C-Brake by Jacobs to back it up. The front living layout puts the King bed in its own private rear suite, and the full bath keeps daily life civilized. Active brake assist, lane departure warning, and a quad-view camera system make the driving experience feel more manageable given the scale. For those who want to go deeper off-grid, the optional Xplorer Package adds 540aH of lithium batteries and a 1,000W solar array, a natural pairing with the self-contained capability the rest of the platform already delivers.
