2021 Grand Design Solitude 378MBS-R Fully Loaded, Off-Grid Ready, Turnkey Full-Time Rig

This is not a stock Solitude. This is a thoughtfully upgraded, real-world, full-time and off-grid capable 5th wheel that would cost $90k+ to replicate today if you were to buy a similar-year used model and upgrade it yourself.

If you've walked RV shows or priced new or used Solitudes lately, you already know--dealer pricing plus lithium, solar, generator, washer/dryer, and connectivity upgrades add up fast. This rig already has it all professionally installed and dialed in.

Factory Option Upgrades Included

- Dual-pane windows (excellent climate & sound insulation)
- Slide toppers
- 8K axles with disc brakes

$26,000+ Off-Grid Power System

- Victron Cerbo GX MK2 + GX Touch 50 display

Run the coach like a small house--ACs, appliances, laundry--without shore power.
