## Overview

The Seismic 403 is built for people who want to bring the toys without sacrificing the comforts. The front bedroom keeps the living space private from the garage, and a loft adds sleeping room without eating into the main floor. A kitchen island gives you actual prep space, and the bath and a half means the crew isn't fighting over one bathroom after a long day on the trails. Two entry doors — one to the living area, one to the garage — are a small detail that makes a big difference when you're loading and unloading.
