    AI summary

    Grand Design's Solitude 377MBS-R is built around a dedicated mid-bunk room that keeps sleeping quarters separate from the main living space, a layout that owners frequently call out as one of its biggest strengths. The residential feel carries throughout, with generous storage and a den area that makes extended stays genuinely comfortable rather than just tolerable. It sleeps nine, so there's real capacity here without the floor plan feeling like it was crammed to hit a number. Full-timers in particular tend to gravitate toward this one for its livability and how well the space actually functions day-to-day.
