## Overview

The rear kitchen layout is what sets the 300ML apart. It's a genuinely large cooking space with an island that anchors the whole back of the trailer, giving you room to actually spread out while preparing meals. Flow through the unit feels open and social, with the kitchen naturally becoming the gathering spot rather than an afterthought. Automatic leveling (BAL 7.3 system) takes the hassle out of site setup, and the six-person sleeping capacity is spread comfortably across the floor plan without everything feeling stacked on top of each other. At 35 feet, it's a substantial trailer that rewards those who want a home-base feel at the campground.
