    AI summary

    The 320G stands out in the toy hauler world by giving the front of the unit to an actual bedroom rather than squeezing sleeping into the garage end. A bath and a half means the full bathroom stays private to the bedroom while guests have their own half bath, a thoughtful split that toy haulers often skip. The loft adds a dedicated sleeping or hangout space, and two entry doors give everyone their own way in and out without cutting through the living area. Under the skin, Grand Design backs this with heavy-duty 8,000lb axles with ABS drum brakes, MORryde CRE3000 suspension, and a sway mitigation system. Gear that actually matches the serious use this kind of hauler gets.
