Owning a used Grand Design Solitude usually runs $4,000 to $9,000 per year once you add up depreciation, insurance, storage, tires, and routine repairs, and that is before any big-ticket surprise like a slide motor or a soft floor. The Solitude is a heavy, full-profile fifth wheel, so the two costs that bite hardest are the truck it demands and the upkeep on its three or four slides. Buy the right unit and your yearly spend is predictable; buy a water-damaged one and a single season can erase the discount you thought you got.
The Solitude sits at the top of Grand Design's fifth-wheel lineup, built for full-timers and long-haul snowbirds. That residential ambition is exactly why ownership cost is more nuanced than a smaller trailer. Below is what to check, what to ask, and what to budget so the sticker price is not the number that surprises you. Want a fast read on a specific unit before you drive out?

What a used Solitude actually costs to buy
Solitude pricing swings hard with model year, floorplan, and how hard it was used. These are honest ranges to research, not quotes, and you should always verify against comparable listings in your region.
| Model year range | Typical used asking range | What drives the spread |
|---|---|---|
| 2015 to 2017 (early) | $28,000 to $42,000 | Older slide mechanisms, higher odds of past water intrusion, dated interiors |
| 2018 to 2020 | $40,000 to $58,000 | Mid-life units, often one owner, mix of full-time and seasonal use |
| 2021 to 2023 | $55,000 to $78,000 | Lower miles on the chassis, newer tires, stronger resale floor |
| 2024 and newer | $72,000 to $95,000+ | Near-new, steep first-owner depreciation already absorbed by seller |
Treat any price well below these ranges as a question, not a deal. A Solitude priced $10,000 under comparable units is usually telling you something: a soft floor, delamination, a salvage or lien history, or a slide that does not seal. Run the numbers honestly with the used RV offer calculator and the RV ownership cost calculator before you anchor on the seller's price.
The truck is part of the ownership cost
This is the line item buyers underestimate most. A Solitude is a full-profile fifth wheel, and most floorplans carry a GVWR in the 14,000 to 16,800 pound range with pin weights commonly between 2,300 and 3,400 pounds. That is one-ton truck territory, often a dually for the larger plans.
If you already own a 3500/F-350 or bigger with a properly rated hitch, great. If you are towing with a half-ton or a light three-quarter-ton, the real cost of Solitude ownership includes a different truck, and that can be $15,000 to $60,000 used. Do not let a salesperson hand-wave this.
- Confirm the loaded pin weight against your truck's payload sticker, not its towing number.
- Budget $800 to $2,500 for a properly rated fifth-wheel hitch if one is not included.
- Run the rig through the RV towability calculator with your specific truck before you commit.
Walk away if the seller insists "any 3/4-ton pulls it fine" without showing you weights. Payload, not marketing, decides whether you tow this safely.
Slides, seals, and the recurring maintenance budget
Most Solitude floorplans run three slides, and the larger plans run four. Slides are the single most expensive moving system on the coach, so they deserve a dedicated line in your budget. Frame this as areas to inspect and reported issues to research, not as asserted failure rates on any given unit.
Buyer concerns to inspect and research on a Solitude:
- Slide seals and toppers: rubber seals dry out and toppers tear. Reseal and topper replacement commonly runs $150 to $600 per slide.
- Slide motors and gears: a failed motor or stripped gear can run $400 to $1,500 installed. Operate every slide fully in and out during inspection.
- Roof membrane and sealant: the single biggest defense against water damage. Plan to re-lap seams yearly; a full roof reseal kit and a day of labor runs $300 to $900.
- Auto-leveling system: convenient and expensive. A bad sensor or pump can run $300 to $1,200.
If you see any slide-out problems (grinding, sticking, gaps at the seal when closed, water staining under the slide floor), get a price quote before you buy and subtract it from your offer. A slide that does not seal flat is a water-damage machine.
Annual routine upkeep on a well-kept Solitude, excluding surprises, typically lands at $600 to $1,500: sealant, slide lube, lubrication, battery care, winterizing, and minor seal work.
Tires, axles, and brakes
Heavy fifth wheels are hard on tires, and tire age matters more than tread on an RV that sits for months.
- Replacement set: a full set of correctly rated fifth-wheel tires runs $800 to $1,600, more for upgraded load-range tires.
- Age over tread: check the DOT date code. RV tires are commonly aged out at five to seven years regardless of how good they look. Read the RV tire age guide before you trust the rubber.
- Bearings and brakes: budget $300 to $700 for a full repack and brake inspection if there is no recent record.
Ask the seller for the date of the last bearing repack and tire purchase. No records usually means you are buying both jobs.
The expensive surprises to inspect for
These are the items that turn a $50,000 trailer into a money pit. None are unique to Grand Design, but the Solitude's size and slide count raise the stakes.
- Water damage and soft floors: press around slide floors, the front cap, window corners, and the bathroom. A soft spot is a major repair, often $1,500 to $6,000+. Use the used RV inspection checklist and read RV red flags.
- Delamination: look down the exterior walls at a low angle for bubbling or waviness in the fiberglass. Delamination signals trapped moisture and a costly repair.
- Appliances: a residential fridge, two AC units, and a furnace are common. AC replacement runs $900 to $1,800 per unit; a fridge can run $1,200 to $3,500.
- Title and lien: never skip the title and lien check. A clean-looking Solitude with an open lien is not yours to register.
Always verify recalls and complaints on the exact unit by make, model, and year through the NHTSA recalls and complaints database. A VIN-level check catches issues a walk-around never will.
How the Solitude compares on cost
Within the Grand Design lineup, the Solitude is the most expensive to feed because it is the largest and heaviest. Compared to other full-profile fifth wheels from Keystone, Forest River, and Jayco, Solitude resale tends to hold a bit firmer, which cuts your depreciation cost but raises your buy-in. If your budget is tight and you do not need the residential space, a smaller fifth wheel or even a half-ton-friendly travel trailer will cost far less to own, mostly because it does not demand a one-ton truck. Browse the full guides library to compare classes before you settle.
A realistic annual ownership budget
Here is a grounded picture for a mid-year used Solitude in seasonal (not full-time) use. Full-timers should expect the high end and then some.
| Cost line | Low | High |
|---|---|---|
| Depreciation (per year) | $1,500 | $3,500 |
| Insurance | $700 | $1,600 |
| Storage (covered) | $600 | $2,400 |
| Routine maintenance | $600 | $1,500 |
| Tires (amortized) | $150 | $350 |
| Repairs and surprises (averaged) | $500 | $2,000 |
| Rough annual total | $4,050 | $11,350 |
Fuel and campground fees are separate and depend entirely on how you travel. The point of the table is the fixed cost of simply owning the unit, which is higher than most buyers guess because of storage, insurance on a high-value coach, and slide upkeep.
Frequently asked questions
Is a Grand Design Solitude expensive to maintain compared to other fifth wheels? Maintenance per system is similar to other quality fifth wheels, but the Solitude has more systems (three to four slides, auto-leveling, two ACs, often a residential fridge), so total upkeep trends higher. Budget $600 to $1,500 a year for routine care and keep a reserve for slide and roof work.
What truck do I need to tow a Solitude, and does that count as ownership cost? Yes, it counts. Most Solitude floorplans need a one-ton truck (3500/F-350 class, sometimes a dually) because of pin weights in the 2,300 to 3,400 pound range. If you do not already own one, factor the truck into your true cost of ownership and verify with the RV towability calculator.
How do I tell if a used Solitude has hidden water damage? Press around slide floors, the front cap, and bathroom for soft spots, look for ceiling and wall stains, smell for mustiness, and inspect the roof seams and slide seals. Sight down the exterior walls for delamination. Use the inspection checklist and walk away from any soft floor you cannot price out.
Does the Solitude hold its value? Relatively well for a full-profile fifth wheel, which lowers your depreciation cost but raises your purchase price. The biggest value killer is deferred maintenance: a leaking roof or a failing slide will sink resale faster than age or mileage.
What should make me walk away from a Solitude listing? A soft or spongy floor, fiberglass delamination, a slide that grinds or will not seal, an open lien, a missing or branded title, or a price so far below comparables that the seller is clearly hiding a problem. Any one of these is a reason to keep looking.
