Description
2020 Grand Design Solitude 377MBS Full-Time / Off-Grid Ready $49,000 OBO
Turnkey luxury fifth wheel with over $20K in upgrades
If you are looking for a rig that is already built for full-time living, long-term travel, remote work or boondocking, this Solitude 377MBS is the one for you! It's in excellent condition, heavily upgraded, and completely ready for the road. It is 40' long, with 4 slides and 2 axels.

Why This Rig Stands Out
This isn't a stock Solitude it's a fully dialed in, off-grid capable home on wheels. The solar + lithium + inverter combo alone is a gamechanger for boondocking. Everything has been maintained meticulously and upgraded thoughtfully.
