## Overview

The 374TH's party trick is its 'invisible garage' — you get real toy-hauling capability without the sacrifice of living space that usually comes with it, making it genuinely usable as a full-timer. Inside, the kitchen earns its keep with a 4-door stainless fridge, professional-grade cooktop with built-in oven, solid surface counters, and real tile backsplash — details that separate this from most fifth wheels at any price. Grand Design's reputation for insulation (R-45 flooring) shows up in owner reports of the Solitude handling extreme weather without complaint, and the power reclining theatre seating, fireplace, and big-screen TV make the living area feel more like a cabin than a trailer. The double tri-fold hide-a-bed sofas handle sleeping six, while the Queen bed with power lift reveals serious under-bed storage below.
