Before You Buy: Get a Third-Party RV Inspection
Do not accept delivery without a full, independent inspection. It is your single best leverage point before you sign. Once you take delivery, many owners report being pushed “to the back of the line” for warranty repairs, with units sitting at dealers for weeks or months, canceling camping trips and burning money on storage and payments while the RV is unusable.
- Hire an NRVIA-certified or highly reviewed independent inspector who is not affiliated with the seller. Use this simple search to find pros near you: RV Inspectors near me
- Make the purchase contract contingent on passing inspection and timely correction of defects in writing.
- Require water intrusion tests, frame/suspension measurements, slide operation stress tests, thermal imaging for hidden leaks, and a full 120V/12V load test.

Patterns of Reported Problems and Risk Areas
Water Intrusion: Roof, Front Cap, Slide Seals, and Windows
(Serious Concern)
Multiple owners across reviews and forums report water leaks in the Solitude S-Class—especially around slide rooms, roof penetrations, front cap seams, and window frames. Early sealant failures or insufficient sealant coverage can allow water to track into walls and floors, leading to soft spots, delamination, warped subfloor, and mold risk.
- Pay close attention to front cap seams and roof terminations; poorly prepped surfaces or thin lap sealant are a repeating theme in owner photos and posts.
- Slide toppers and bulb seals can mask slow leaks. Inspect both sides of slide floors and the underbelly for water staining.
- Search threads and owner videos: YouTube: Solitude S-Class water leak issues and Google: Solitude S-Class water leaks.
Documented water ingress, even when repaired, can permanently reduce resale value. Verify every inch with moisture meters during your pre-delivery inspection.
Independent creators like Liz Amazing often highlight the long-term cost of missed water intrusion—search her channel for “sealant,” “slide leaks,” and “Grand Design.”

Frame Flex, Pin Box Area, and Suspension/Axle Alignment
(Serious Concern)
Several fifth-wheel brands have faced “frame flex” reports at the pin box/front cap area; owner posts suggest similar concerns can appear in the Solitude line, including S-Class variants. Symptoms include cracking around the front closet, shifting doors, popping noises over bumps, or visible cap separation under load. Axle misalignment, bent axles, or uneven tire wear also show up in complaint clusters.
- Watch for early cupping or inside edge wear on OEM tires—a red flag for alignment issues or overloaded axles.
- Ask the dealer for alignment documentation and the axle manufacturer’s spec sheet; verify U-bolt torque and spring pack hardware condition.
- Research similar reports: Google: Solitude S-Class frame flex, YouTube: S-Class suspension problems, and forum threads at RVForums.com.
Alignment and frame issues can cascade into costly tire replacement, brake wear, and unsafe towing behavior. These are not cosmetic defects—treat them as structural and safety-critical.
Slide-Out Mechanisms: Schwintek/RAM Track Failures and Seal Problems
(Moderate Concern)
Owners report slide rooms getting out of sync, binding, or failing to fully seal. Track-driven systems can be sensitive to alignment and loading. If the room is even slightly racked, motors can strain, gears can strip, or seals may wear prematurely, allowing water ingress and drafts.
- Test all slides repeatedly at PDI under shore power and battery power; listen for binding or uneven motor pitch.
- Inspect wiper and bulb seals for uniform contact. Look for daylight, torn corners, or sealant gaps.
- References: YouTube: Solitude S-Class slide-out problems; Good Sam: S-Class slide issues.
Electrical System Faults: Breakers, GFCIs, Transfer Switches, and Wiring Cleanliness
(Serious Concern)
Owner threads commonly surface issues such as tripping GFCIs, loose neutral/ground connections, improperly crimped lugs, and transfer switch or inverter/charger problems that devolve into intermittent power loss. Chafed wires behind panels or underbelly harnesses can create fire risk.
- Insist on a full-load test at PDI: run the microwave, ACs, water heater (electric), and outlets simultaneously to identify weak points.
- Have the inspector open the distribution panel and transfer switch enclosure to verify torque and strain relief on all conductors.
- Research: r/RVLiving: S-Class electrical problems and YouTube: S-Class electrical issues.
For context on how common electrical workmanship misses can be, review consumer advocates like Liz Amazing and search her channel for “transfer switch,” “wiring,” or “inspection.”
HVAC, Insulation, and Condensation Control
(Moderate Concern)
While the S-Class is positioned as “residential,” owners in colder or humid climates report insufficient insulation at pass-throughs, slide floors, and around windows. Poor duct sealing, crushed ducts, or inadequate return air can reduce HVAC performance and cause condensation around vents and behind furniture.
- Remove registers during inspection to check for collapsed or kinked duct runs. Use an infrared thermometer to map temperature differentials.
- Look for evidence of sweating on metal frames and window tracks after an overnight AC run; persistent condensation can feed mold.
- Resources: Google: S-Class insulation problems and RVInsider: HVAC complaints.
Plumbing: PEX Fittings, Leaks at Manifolds, and Tank Sensors
(Moderate Concern)
Leaks at crimped PEX connections, under the bathroom vanity or kitchen sink, and behind the Nautilus panel are regularly reported. Fresh and waste tank sensors often give inaccurate readings after limited use, complicating boondocking and site departures.
- Pressurize the system and inspect every accessible PEX joint; run hot water to expand connections. Look for pinhole leaks and weeping.
- Cycle tank flush systems and monitor for leaks at the backflow preventer; confirm the city water check valve seals properly.
- Owner evidence: Good Sam: S-Class plumbing problems, Reddit: plumbing issues.
Appliances: Refrigerators, Furnaces, Water Heaters, and Stovetops
(Moderate Concern)
Owners cite intermittent operation and early failures for both gas-absorption and 12V refrigerators, furnace ignition issues, and water heater control board problems. While many of these components come from third-party suppliers, the net experience for the consumer is downtime and fights over who pays—dealer, supplier, or manufacturer.
- Request documentation on the appliance models installed. Search for past recalls or TSBs by brand and model number.
- Run extended appliance cycles during PDI: freeze test for the fridge, multiple furnace start cycles, and water heater operation on both gas and electric.
- Search trails: Google: S-Class refrigerator problems.
Fit-and-Finish: Cabinetry, Trim, Flooring, and Hardware
(Moderate Concern)
Despite the S-Class positioning, owners have posted examples of misaligned cabinet doors, staples protruding through trim, bubbles or delamination in vinyl flooring, and drawer slides pulling free. Cosmetic, yes—but they signal rushed assembly and can be time-consuming to rectify.
- Open every drawer and cabinet, load them with weight, and travel-test if possible to check for racking or loose fasteners.
- Run a bright inspection light along floor seams and under slide lips to catch early lifting.
- Evidence threads: r/GoRVing: quality issues, RVInsider complaints.
Weight Labels, Cargo Capacity, and Towing Realities
(Serious Concern)
Some buyers discover after delivery that real-world pin weight and loaded weights leave minimal margin for their truck’s payload, rear axle rating, or tire capacity. On a fifth wheel, this is both a safety and liability issue.
- Insist on a certified scale ticket for the exact unit (with and without water) to validate the yellow sticker claims. Compare to your truck’s payload and RAWR.
- Remember: adding batteries, solar, washer/dryer, and cargo adds up quickly and shifts weight forward to the pin.
- Research: Google: S-Class weight problems.
Tires, Brakes, Bearings, and Wheel-End Heat
(Serious Concern)
Premature tire wear, blowouts, and hot hubs have been reported by a subset of owners. In many cases the root cause is alignment or loading; in others, brake adjustment or poor bearing service from the factory is implicated.
- Have an independent shop check brake adjustment and bearing preload before your first long tow.
- Use an IR thermometer at each fuel stop to spot a hot hub early.
- Owner discussions: Reddit: S-Class tire problems.
Warranty Processing, Parts Delays, and Dealer Backlogs
(Serious Concern)
A dominant theme across negative reviews is service throughput. Owners describe long waits for parts authorization, limited technician availability, and units sitting for weeks or months, especially during peak season. Disputes over whether a defect is “component supplier” or “OEM” responsibility can stall repairs.
- Get turnaround commitments in writing and ask the dealer to disclose their current service backlog.
- Consider mobile RV technicians for triage and documentation; some repairs can be authorized outside the dealer channel.
- Evidence sources: BBB search: Grand Design Solitude S-Class, RVInsider complaint patterns.

Cost of Ownership: Early Repairs, Depreciation, and Opportunity Cost
(Moderate Concern)
Even if warranty covers parts and labor, weeks of downtime can sink camping plans and create hotel or storage expenses. Units with early water damage or structural fixes can take a resale hit; future buyers will ask for receipts and photo documentation.
- Keep meticulous records of every repair, part number, and service ticket.
- Consider extended service plans cautiously; read exclusions for “seals and gaskets,” “maintenance,” and “adjustments.”
Overpromised Amenities vs. Real-World Execution
(Moderate Concern)
Luxury-feel marketing can clash with actual execution: fireplaces that trip breakers under load, entertainment wiring loops that hum, or “residential” furniture that peels after a season. Owners report features feeling more like options than guarantees.
- Operate every amenity at once during PDI: TVs, sound, fireplace, microwave, ACs, water heater, lights. Look for dimming or tripping.
- Inspect furniture stitching and seat coverings; look for early peeling or loose threads.
- Search: Google: S-Class complaints.
Safety Recalls and What They Mean for You
RV fifth wheels fall under NHTSA’s purview for safety recalls. Owners should check their exact VIN for open recalls and skim recall language to understand the failure mode and remedy. Visit: NHTSA Recalls: Grand Design Solitude S-Class.
- Common recall themes in the wider fifth-wheel category include propane components (regulators/hoses), brake assemblies, axle hardware torque, and labeling errors that can impact safe loading. Your VIN lookup will show whether your S-Class is affected and how the remedy is performed.
- Act promptly on recalls. Document dealer communications and expected parts timelines. If a safety recall is delayed due to parts availability, ask the manufacturer for interim safety guidance.
Cross-check owner video documentation of recall service experiences: YouTube search: Solitude S-Class recall. For a wider industry view on recalls and owner rights, browse the consumer-focused analyses on the Liz Amazing channel and search her library for “recall,” “NHTSA,” or your year/model.
Legal and Regulatory Warnings
Several complaint patterns raise potential legal exposure for the manufacturer and selling dealers:
- Magnuson–Moss Warranty Act (federal): Requires clear written warranties and prohibits tying warranty coverage to use of specific brands of parts/services. If warranty repairs are unreasonably delayed or denied for covered defects, consumers may have remedies. Document all communications.
- State lemon laws and RV-specific statutes: Coverage varies widely; some states exclude towables while others include them. Even where lemon law does not apply, state consumer protection laws against unfair or deceptive acts and practices (UDAP) can be relevant, especially for misrepresentation of quality or failure to honor warranty terms.
- FTC enforcement: Advertising claims that imply “residential quality,” “four-season,” or “industry-leading warranty” may be scrutinized if owner experiences consistently contradict those claims without adequate disclosure.
- NHTSA obligations: Safety defects must be remedied under recall. If you encounter a defect that presents a safety hazard and is not covered by a recall, file a report at NHTSA. A pattern of reports can trigger investigations.
If your unit has been out of service an unreasonable number of days for warranty repairs, consider consulting a consumer protection attorney who understands RV cases. Keep an evidence file with dated photos, technician notes, and written timelines. Have a story others should hear? Post your experience so shoppers can learn.
Product and Safety Impact Analysis
Based on aggregated owner reports, the most consequential risks in the Solitude S-Class center on water intrusion, frame/suspension alignment, and electrical workmanship. Here’s how those defects translate into real-world safety and financial risk:
- Water intrusion compromises structural materials and can lead to hidden rot and mold. In a fifth wheel, persistent leaks around the front cap or slide rooms can undermine the floor structure and resale value, sometimes totaling out the unit’s long-term viability.
- Frame flex/alignment problems can induce unpredictable handling, tire blowouts, and braking inconsistencies. Misalignment accelerates wear and increases the risk of a catastrophic tire failure at highway speed.
- Electrical faults carry fire risk and can strand owners without heat, refrigeration, or essential systems for travel safety. Poorly torqued lugs or chafed wiring in a moving trailer is a serious hazard.
- Service delays magnify costs. Even covered repairs can leave families without their RV for peak season, resulting in lost booking fees and alternative lodging costs.
The intersection of these issues is critical: a unit with minor water leaks and a backlog for service can snowball into major structural repair by the time an appointment opens. That’s why a rigorous pre-delivery inspection is non-negotiable. Search for professionals: RV Inspectors near me.
Balanced Note: Reported Positives and Manufacturer Responses
To be fair, some Solitude S-Class owners report positive experiences—complimenting floor plans, storage, aesthetic finishes, and strong initial customer service interactions. There are accounts of Grand Design authorizing mobile tech repairs and shipping parts quickly in certain cases. Owners also point to an active company presence in some owner forums, which can help escalate fixes.
However, the breadth of complaints about workmanship and service bottlenecks suggests outcomes are inconsistent. Even when issues are addressed, the total time and effort asked of consumers can be substantial. Your personal result may vary depending on dealer competence, service center queue length, and the specific defects on your unit.
Actionable Pre-Purchase Checklist for the Solitude S-Class
- Independent inspection first: Book a pre-purchase inspection with a qualified third party; don’t rely on dealer PDI. Search: RV Inspectors near me

Final Summary and Verdict
The Grand Design Solitude S-Class delivers popular floor plans and an upscale feel at a price point below the full Solitude line. Yet our analysis of publicly available owner reports identifies recurring, substantive concerns that prospective buyers should weigh heavily: water intrusion at critical seams and slide rooms; frame and alignment issues contributing to tire wear and towing risk; electrical workmanship faults; plumbing leaks; and, crucially, drawn-out warranty timelines that can sideline the RV during peak season. While some owners report satisfactory resolutions and positive experiences, the consistency of these negative themes across forums, video reviews, and complaint repositories suggests material risk to both safety and financial outcomes.
To make the most informed decision, study the resources linked throughout this report:
YouTube search,
Google search,
BBB,
RVInsider,
and NHTSA recalls. For consumer-defense strategies and real-owner case studies, consider searching the Liz Amazing channel for Solitude S-Class content.
Given the weight of verified complaints and the potential for costly downtime, we do not broadly recommend the Grand Design Solitude S-Class without a rigorous, independent inspection and ironclad repair commitments. Risk-averse shoppers should test-drive other brands and models known for stronger QC and shorter service queues before deciding.
