## Overview

What stands out about the 355G is how much Grand Design managed to include without padding the weight — standard solar and a 12V refrigerator come built in, not as add-ons. The front bedroom keeps your sleeping quarters well away from the garage end, and the single full bath sits in between, which makes the layout feel more intentional than most toy haulers at this price point. The G-Class trades a few premium touches found on the M-Class (like dual-pane windows) to hit a lower weight and cost target, but it doesn't feel stripped down doing it. Grand Design's plumbing reputation is notably strong across the Momentum line, which matters when you're running water systems hard on the road.
