What stands out immediately about the 377MBS is how livable it feels for a rig that sleeps nine. Owners consistently describe it as apartment-like rather than camper-like, with smart storage and a layout that doesn't feel cramped even with a full bunkhouse in the mix. The mid-bunk configuration keeps the sleeping area separate from the main living space, and creature comforts like heated bathroom floors and distributed heating and cooling make it genuinely comfortable across seasons. Grand Design's build quality on the Solitude line has earned a strong reputation for towing stability. Owners report confidently running at highway speeds without drama. If you're hauling a large crew and don't want to sacrifice the niceties, this one's worth a close look.
