Before you buy: get a third-party RV inspection

We strongly recommend hiring an independent NRVIA-certified or equivalent inspector to perform a comprehensive pre-purchase inspection. This is your leverage—before you sign. After delivery, dealers and service centers can (and often do) place you at the back of the queue, especially during peak season. Numerous owners report missed holiday trips because their new van sat at a dealer for weeks or months awaiting parts or authorization. To find a candidate locally, run this search: Search Google for “RV Inspectors near me”. Ask the inspector to water-test the roof and openings, load test batteries, test generator under load, verify propane and CO detectors, weigh the van if possible, and validate every appliance and control system.

At delivery, do not rush. Conduct your own 2–3 hour “live” shakedown at the dealership with city water and tanks filled, shore power connected, then disconnected. Document any deficiencies on the due bill before making final payment. If the dealership pressure is on, remember: you have the most leverage before you sign. For added peace of mind, you can also schedule a second inspection immediately after purchase while the return-to-service window at the selling dealer is still open: find another inspector near you.

Reported build-quality and livability problems on the Thor Scope

Water leaks, wet bath failures, and moisture control

Owner accounts commonly describe leaks in and around the wet bath, including loose PEX fittings, undersink drips, poorly sealed shower pans, and water intrusion at roof penetrations that migrate down wall cavities. Some report visible staining, soft flooring near the bath, or musty odors. Persistent leaks can lead to mold and delamination—expensive fixes that insurers sometimes treat as maintenance-related. Watch for swelling cabinet bases near the bath and verify a dry subfloor after extended shower use. See threads and videos: Google: “Thor Motor Coach Scope Water Leaks”, YouTube: “Scope Leaks”, and forum-based owner reviews: RVInsider “Scope Problems”.

If you’ve dealt with moisture or mold in a Scope, can you describe how it was resolved and the total cost or downtime?

Roof and sidewall penetrations: sealant gaps and recurring re-seal needs

Reports point to inconsistent caulking around roof racks, awning mounts, ladder mounts, and antenna/solar penetrations. Even a pinhole allows capillary water ingress in a van. Inspect the sealant quality on delivery; if it’s sloppy or thin, demand rework. Owners on forums often cite periodic resealing becoming a routine maintenance chore in the first year. Cross-check similar Thor Class B threads to understand the maintenance cadence: Reddit r/rvs: “Scope Problems”, and Good Sam: “Scope Issues”.

Cabinetry, hardware, and fastener failures during travel

On-road vibration exposes corners cut in cabinet construction. Owners note misaligned latches, hinges pulling out of thin substrate, and drawers that open while driving. A common DIY fix is reinforcing screws and adding secondary latches or magnetic catches. Before acceptance, drive the van on uneven roads, then re-check every latch. Document anything that pops open for warranty attention. For examples, see: Google: “Scope Cabinet Problems”.

Electrical and multiplex control issues (Rapid Camp+/BMPro-style panels)

Many Thor vans use an integrated control panel to manage lights, water pump, awning, and generator. Owners report panels freezing, phantom tank readings, and 12V circuits dropping out until a hard reboot (power cycling the coach battery disconnect). Sometimes the panel misreports tank levels and battery status, leading to preventable shutdowns during boondocking. Ask for the panel’s brand and model, confirm latest firmware, and verify that a physical bypass exists for essentials (water pump and lights). Compare multiple owner threads here: YouTube: “Scope Electrical Problems”, r/GoRVing search “Scope Electrical”.

12V charging, battery management, and solar limitations

Owners frequently flag weak alternator charging to the house battery bank and failures of the battery isolation manager (BIM) or DC-DC charger. Symptoms include a generator that runs but fails to effectively replenish batteries, or solar panels that cannot keep up with parasitic loads and refrigeration. Marketing touts “off-grid capability,” but real-world autonomy can be far less without upgrades. Confirm the exact battery chemistry (AGM vs. lithium), amp-hours, the DC-DC charger rating, and whether solar is MPPT or PWM. See aggregated complaints: Google: “Scope Battery Problems”, Good Sam: “Scope Solar Issues”.

Generator and shore power reliability

Small gasoline generators (often Onan) in Class B vans can be fussy about warm starts, altitude, and load changes. Owners report hard starts, surging under A/C load, or shutdowns due to clogged spark arrestors or fuel pickup quirks. A shore power transfer switch or GFCI nuisance trip problem occasionally presents as “no power” on arrival. Insist on a full generator demonstration under air-conditioner load and verify shore power transition. Owner videos and comments: YouTube: “Scope Generator Problems”.

HVAC performance: roof A/C, furnace/water heater combo, and ducting

Reports include underperforming roof A/C in sun-exposed climates and rattling A/C shrouds, plus intermittent ignition or control board faults in the combo furnace/water heater. Poorly sealed ducting can further hurt performance. Ask the dealer to record supply/return temperature delta and address any short-cycling before delivery. Cross-check: Google: “Scope AC Problems”, and threads via RVForums.com.

Doors, windows, and noise: slider alignment, rattles, and water ingress

Multiple owners mention poorly aligned sliding side doors that rattle on highway joints or fail to close flush, leading to wind noise and occasional water entry in heavy rain. Window weep holes clogging or mis-sealed frames can drip into wall trim. On the test drive, listen for rattles around 50–65 mph and run a hose test along the slider and rear doors. See examples: Google: “Scope Door Rattle”.

Plumbing odors, tank sensors, and venting

False tank level readings are widely reported across many RVs, and the Scope is no exception. Bad reads complicate boondocking. Some owners also describe sewer odors traced to air admittance valves or roof vent terminations. During PDI, run water to 50% on both gray and black tanks and validate sensor behavior. Search for field fixes and owner outcomes: Good Sam: “Scope Tank Sensor Problems”, Reddit r/rvs: “Scope Smell”.

Chassis and safety issues tied to the Ram ProMaster and Thor integrations

NHTSA recalls: rearview camera display, safety systems, and component defects

ProMaster-based vans (including those upfitted by Thor as the Scope) have seen recurring recalls in recent model years, such as intermittent or blank rearview camera images, airbag/seatbelt concerns, or lighting/control module glitches. A non-functional camera significantly increases backing risk. Owners should run their VINs regularly: NHTSA: Thor Motor Coach Scope. Also search owner discussions where recall remediation delays affected planned trips: Google: “Scope Recall”.

Weight, payload, and stability under real-world loading

Compact Class B vans often operate close to GVWR once water, passengers, gear, and aftermarket items are added. Owners report wallowing in crosswinds, frequent bottoming on driveways, and uneven tire wear. Some add helper springs or SumoSprings; others discover their cargo capacity is slimmer than expected. Weigh the van fully loaded at a CAT scale and compare axle weights to the sticker. Learn from owner measurements: r/GoRVing: “Scope Weight”, Google: “Scope Payload”.

Powertrain, drivability, and MPG expectations

Although the ProMaster’s V6 and later 9-speed automatic improved drivability, owners of upfitted vans still report modest fuel economy (often in the teens) and extended downshifts on grades. This is less a defect than a reality of physics: boxy campers and added weight cost MPG. Still, some shoppers feel marketing downplays this. Review long-term driving impressions here: YouTube: “Scope Driving Review”.

Warranty experiences and service delays

Long repair queues, parts delays, and dealer/manufacturer handoffs

A dominant theme in BBB complaints and forum threads is extended downtime after purchase for punch-list items, with dealers citing manufacturer authorization or parts availability as the bottleneck. Some owners report vans sidelined for weeks or months within the first season, forcing canceled trips. Survey these patterns in public filings and threads: BBB search results for Scope, Google: “Scope Warranty Complaints”, and aggregated stories on PissedConsumer (search “Thor Scope”).

Price, options, and value-versus-marketing gaps

“Off-grid ready” claims versus real autonomy

Several owners found the factory solar and battery bank insufficient for extended boondocking without frequent generator use. Marketing often highlights “off-grid” imagery, but realities like parasitic loads, fridge duty cycles, limited solar harvest, and small alternator charging can cut trips short. Budget for upgrades (lithium, DC-DC charging, more solar) if you need genuine off-grid stays. Cross-check field reports here: Good Sam: “Scope Boondocking Problems”, YouTube: “Scope Off Grid”. Also see consumer advocacy content on Liz Amazing’s channel calling out RV hype; search her channel for the specific model you’re considering.

Overpriced add-ons and dealer-installed accessories

Buyers frequently encounter addendum sheets with high-margin add-ons (paint protection, nitrogen fill, anti-theft etching) that add little real-world value. Say no. Apply those funds to a real battery/solar upgrade or professional sealant inspection instead. Compare buyer experiences: Google: “Scope Dealer Add Ons”.

Recall watch and safety bulletins

How to verify recall status and protect your VIN

Run an NHTSA recall search by VIN before purchase and periodically after: NHTSA recall page. Match recall bulletins to your exact year and floorplan; chassis recalls (Ram) and coach recalls (Thor) may be separate. Owners sometimes report slow parts pipelines for recall fixes; log your contact with both Thor and the Ram dealer, and ask for estimated parts ETAs in writing. For recap of recent recall chatter, scan: Google: “Scope Recall Issues”.

Legal and regulatory warnings

Know your rights under warranty and consumer law

Motorhome warranties are governed by the Magnuson-Moss Warranty Act, which requires manufacturers to honor the written warranty and not disclaim implied warranties in certain states. However, RVs combine a chassis (Ram) with a coach (Thor), and each has separate warranties and service networks. If a defect is not fixed within a reasonable number of attempts or a reasonable time, depending on your state you may have remedies under state lemon laws (coverage for motorhomes varies widely) and under the Uniform Commercial Code’s implied warranty of merchantability. Document every visit, written complaint, and downtime day.

Regulatory bodies to know:

• NHTSA: For safety defects and recalls. Submit complaints if a defect affects safe operation.
• FTC and State Attorneys General: For deceptive marketing or warranty violations.
• BBB and private mediation/arbitration: For dispute resolution and paper trails that help if you escalate.

Consult consumer rights resources and consider an attorney if safety defects persist. For research and context, triangulate complaints here: BBB search for Thor Motor Coach Scope, Reddit r/RVLiving complaints, and Google: “Scope Warranty Issues”.

Product and safety impact analysis

How reported failures translate into real risk

Water ingress can quietly undermine structural integrity and air quality, making early leak detection and remediation critical. Electrical control failures in multiplex systems can strand owners without lights or critical pumps when boondocking. Generator instability under A/C load poses heat risks in warm climates—especially if a pet is aboard and owners rely on remote monitoring. Door misalignment and camera outages raise on-road safety risk; a blank camera display or water-compromised brake light wiring amplifies accident exposure.

Financially, long service queues and repeat dealership visits erode the value proposition of a “ready-to-camp” van. First-year depreciation on motorized RVs can be steep; compounding that with months of unusable time is a double hit. Owners who self-upgrade batteries and solar to achieve promised autonomy add thousands to sunk cost. Carefully weigh these impacts before committing.

What Thor has improved or responded to

Incremental updates and reported fixes

Some model years gain chassis improvements from Ram (e.g., transmission and driver-assist technology updates) and occasional component swaps or firmware updates for control systems. Owners report that diligent dealers can correct misaligned doors, reseal roof penetrations, and replace failing control modules under warranty. However, experiences vary dramatically by dealership. Verify what’s changed for your targeted model year and request written confirmation of component brands and software versions. Watch independent walk-throughs and follow consumer advocates who track improvements and defects, such as Liz Amazing’s investigations into RV quality trends. Then, search her channel for the Scope specifically.

Action checklist for shoppers and current owners

• Hire an independent inspector: Before signing, schedule a thorough inspection and water test: Find RV inspectors near you.
• VIN check and recall plan: Run your VIN at NHTSA and ask the selling dealer for a written statement that all open recalls are closed: NHTSA recall search.
• PDI road test: Drive at highway speeds on rough pavement; check for door rattles, wind noise, and alignment issues.
• Power systems validation: Under dealer supervision, run the A/C on generator for 20–30 minutes and monitor voltage. Confirm transfer switch operation when plugging/unplugging from shore power.
• Electrical controls: Power-cycle the multiplex panel and ensure a manual backup for water pump/lights exists if the panel fails.
• Leak check: Hose test roof and door seals; inspect under-sink and wet bath seams after sustained water use.
• Weigh the rig: With full gear and water, visit a CAT scale; compare to GAWR/GVWR and adjust load or suspension.
• Community due diligence: Read recent threads and reviews:
  RVInsider: Scope Problems,
  Good Sam: Scope Problems,
  Reddit r/rvs,
  YouTube reports.
• Escalation playbook: If defects persist, file with NHTSA for safety issues, open a BBB case, and contact your state AG and the FTC for warranty/advertising concerns. Keep a logbook.

Balanced note: not every unit, not every dealer

Why experiences vary so widely

Some Scope owners report good experiences, especially when paired with attentive dealers who do meticulous PDIs and prioritize early fixes. Thor’s supply chain and component vendor changes over model years can also lead to variance. That said, the sheer volume of similar complaints about leaks, electrical controls, charging limitations, and service delays points to systemic, not isolated, issues. Prospective buyers should assume they’ll shoulder some early-life debugging and plan time and budget accordingly.

Bottom line for shoppers

Risk summary: The Thor Motor Coach Scope offers a compact footprint and an attractive price relative to premium Class B vans. Yet, owner reports reveal a recurring pattern of water intrusion risk, inconsistent finish quality, electrical/multiplex glitches, modest off-grid performance without upgrades, and significant service delays on warranty work. Safety recalls on the underlying ProMaster platform and intermittent rearview camera issues add further diligence requirements.

Recommendation: Based on the weight of recent owner complaints and the pattern of service delays, we do not recommend the Thor Motor Coach Scope for buyers who want a trouble-free, ready-to-camp van in the first year. If you proceed, do so only with a thorough third-party inspection, a written PDI punch list, and eyes open about likely upgrades. Otherwise, consider cross-shopping other brands or models with stronger build-quality reputations and quicker service support.
