Based on publicly available records, this appears to be a privately owned, single-location dealership serving the St. Louis region—not part of a national chain.

Find Unfiltered Owner Feedback (Forums, Groups, and Independent Voices)

To get a balanced view, consumers should look beyond star ratings and read detailed accounts from owners who’ve lived with the RVs they bought—especially from the same brands sold by this dealership.

• Facebook owner groups: Join model-specific and brand-specific communities for the RV you’re considering. Use this Google search and insert your brand/model (e.g., Jayco, Forest River, Winnebago): Find RV Facebook Groups via Google Search. These groups often share purchase experiences, service timelines, and warranty outcomes.
• YouTube investigations: Independent creators routinely document dealer-specific patterns. See Liz Amazing’s RV consumer advocacy videos and search her channel for the dealership or RV brand you’re considering.
• Reddit and RV forums: Read threads documenting real-world service timelines, parts availability, and dealer handling of warranty claims. We list direct search links later in this report.

Critical Tip: Arrange a Third-Party RV Inspection Before You Sign

One of the most effective ways to avoid expensive post-purchase surprises is to hire an independent RV inspector before signing final paperwork or taking delivery. A comprehensive inspection can reveal water intrusion, soft floors, roof and sealant issues, undercarriage damage, slide and leveling system defects, electrical anomalies, faulty appliances, and improperly executed prior repairs—issues that can easily cost thousands if discovered after the sale.

• Book your inspector early: Find a certified professional using this query: Search “RV Inspectors near me”.
• Make the sale contingent on inspection results: Your leverage is greatest before you sign. If defects are found, you can walk away or require repairs in writing with a clear timeline.
• Red flag: If any dealership refuses to allow a third-party inspection, you should treat that as a major warning sign and consider walking away.
• Why urgency matters: Without a pre-delivery inspection, owners often discover issues only after a first trip—then their RV can sit in a service queue for weeks or months, disrupting travel plans. This is a common storyline across low-star dealer reviews nationwide. Have you experienced lengthy post-sale repair delays?

What Consumers Report About M.B. Thomas RV Sales, Inc. (St. Louis)

The following sections summarize recurring themes in low-star public reviews and forum discussions regarding this specific location. For the clearest evidence, go to their Google Business Profile and sort by “Lowest rating”: Read negative reviews for M.B. Thomas RV Sales, Inc. Always verify the timing of complaints and whether the dealership responded or resolved the issue.

Sales Experience: Pricing Transparency and “Add-On” Costs

Multiple low-star consumer narratives across the RV sector—including reports referencing this location—describe frustration about final drive-out cost versus the initial advertised price. Common complaints include discovery of dealer add-ons late in the process (prep fees, documentation fees, nitrogen tire packages, paint or fabric protection, and various “security” packages). Some reviewers say they felt pressured to purchase extended service contracts or were told certain add-ons were mandatory. Others report being quoted much higher monthly payments than expected, only to later learn the interest rate or loan term had significantly changed.

• What to do: Request a full, line-item purchase order in writing before you travel or invest time in a deal. Ask the finance manager for a base, no-add-on scenario.
• Don’t be rushed: If you see unrequested add-ons, demand removal, or be ready to walk.
• Compare the APR: Get preapproved financing from your credit union first; compare dealer-offered APR and fees to ensure no rate markup.

To see how other buyers describe their sales experience in their own words, consult the dealership’s Google page and sort by “Lowest rating.” Have you seen unexpected add-on charges at closing?

Low-Ball Trade-In Valuations and Appraisal Discrepancies

Some customers say they received substantially lower trade-in offers on-site than what was discussed over the phone or email. Others report that once their RV or tow vehicle was present, new deductions were raised for cosmetic or mechanical items they felt were normal wear and tear. These scenarios increase the risk of last-minute renegotiation pressure when the buyer has already invested time traveling to the dealership.

• Protect yourself: Provide detailed photos and maintenance records in advance. Request an appraisal range in writing and ask the dealer to specify what could change that estimate.
• Have a backup plan: Get wholesale bids from multiple sources or consider a consignment to benchmark values.

Financing and Interest Rate Markups

In negative reviews across the industry and in some accounts referencing this location, buyers complain their interest rate was higher than expected, or they later discovered better rates were available from local credit unions. Dealers may legally earn reserve (a markup) on loans they arrange. However, consumers should demand transparent, written comparisons.

• Best practice: Arrive preapproved from your bank or credit union. Use that as your benchmark.
• Check for add-on financing products: Ensure GAP, credit life, tire/wheel, and extended warranties are optional and priced competitively.

Paperwork and Title Delays

Delayed titles or registration mishaps appear in low-star reviews at many RV dealerships and are a serious source of owner stress. Some buyers report being unable to use their RV legally for weeks while waiting for plates or temporary permits to be corrected. Others describe multiple return trips for missing signatures or incorrect titling information. In Missouri, the Department of Revenue sets titling guidelines; consumers can reference these if a delay becomes excessive.

• Know your rights: See Missouri DOR’s titling resources for current requirements: Missouri Vehicle Titling (Mo DOR).
• Protect yourself: Get a written estimate on title processing timelines. Insist on copies of everything you sign, and verify VIN accuracy on all forms.
• Escalation path: If a title delay becomes unreasonable, contact the Missouri Attorney General Consumer Protection Division to file a complaint: Missouri AG Consumer Complaints.

Pre-Delivery Inspection (PDI) Quality and Missed Defects

Reports tied to this dealership and many others emphasize disappointing PDIs: new owners found water leaks after first rain, slides binding, leveling jacks inoperative, electrical faults, propane leaks, heater or A/C failures, or trim and sealant problems that should have been caught. Whether buying new or used, a robust PDI is essential, and you should perform your own walkthrough checklist accompanied by photos and video.

• Bring an inspector: Schedule a pro using this search: Find a certified RV inspector.
• Don’t rush delivery day: Allocate at least 2–3 hours. Test all systems: water, electrical, air, slides, generator, hitching, and roof seals.
• Delay pickup if needed: Do not accept delivery until defects are repaired and verified. Get commitments in writing.

Service Backlogs, Parts Delays, and Warranty Approvals

One of the most frequent pain points across RV dealerships is service delays. Consumers report scheduling challenges, parts on backorder, multiple visits to fix the same issue, and communication gaps while the RV sits for weeks. Some say they missed planned trips because their RV was in the shop far longer than expected. Others allege slow or inconsistent warranty claim handling.

• Get timelines in writing: Ask for a written estimate of repair time and whether parts are in stock.
• Use the manufacturer warranty process: If warranty repairs stall, call the RV manufacturer’s customer service for escalation.
• Document everything: Keep a diary of repair visits, dates, and communications. This evidence helps if you escalate to the manufacturer, the BBB, or the AG’s office.
• Pro tip: Independent voices like the Liz Amazing channel exposing RV industry pitfalls discuss how to navigate warranty logjams and protect your travel season.

Extended Warranties and Add-On Products

Some owners regret purchasing extended service contracts, paint/fabric protection, or tire/wheel packages due to unclear coverage or denied claims. Read every term: what’s covered, what’s excluded, required maintenance proof, caps, deductibles, and whether labor hours follow industry guidebooks.

• Compare prices: You can buy many protection plans from third parties—shop around before agreeing in the finance office.
• Ask for the full policy PDF: Avoid one-page brochures. You need the full contract terms before you decide.
• Consumer tip: See independent advice and dealership case studies on Liz Amazing’s RV consumer advocacy channel.

Communication and Post-Sale Responsiveness

Several low-star reviews reference difficulty reaching someone after the sale, unanswered voicemails, or slow updates on parts and repair ETAs. For buyers traveling long distances for pickup, this can be especially frustrating if issues arise quickly on the maiden voyage.

• Set communication expectations: Ask who your single point of contact will be and the expected update cadence (e.g., weekly by email).
• Use written channels: Follow calls with brief emails summarizing what was said and next steps. Paper trails matter.

Safety and Product Risk: Real-World Consequences of Missed Defects

Mechanical or structural issues missed at delivery can translate into real safety risks: axle or tire problems at highway speed, gas leaks, electrical shorts or overheating, water intrusion leading to mold/rot, or unlatched slide rooms extending under motion. Owners should check VINs for open recalls, and confirm completion before finalizing the sale.

• Check recalls by brand/VIN: Visit NHTSA and verify no open recalls remain before delivery: NHTSA Recall Lookup. You can also search recalls and defect investigations broadly by dealership context here: NHTSA recall search formatted for dealership-context queries.
• Independent walkthroughs prevent risk: Third-party inspections frequently catch propane and electrical hazards. Book yours early: Find local RV inspectors.

Balanced Note: Any Indications of Improvement?

In fairness, some reviews do show positive experiences—timely service resolutions, helpful salespeople, or used RVs delivered as described. When dealers respond publicly to negative feedback and invite direct contact to resolve issues, that can reflect a willingness to improve. If you decide to shop here, document your expectations in writing and give the dealership a clear opportunity to address any issues before you finalize the deal. That said, you should still treat the risk areas detailed above as actionable, and take your own steps to verify condition and terms.

Context for First-Time Buyers: Why These Problems Are So Common

RV dealer ecosystems differ from automotive in meaningful ways. Many RVs are constructed by multiple sub-suppliers using materials that must flex and seal under travel stress. Quality control varies widely. As a result, new and used RVs frequently require “shake-down” repairs within early months of ownership. Parts logistics, manufacturer authorization for warranty, and seasonal volumes can elongate repair times. Dealers often juggle warranty approvals, third-party contracts, and technician scheduling, which makes communication and documentation critical for owners. These structural realities do not excuse poor service or deceptive practices, but they do explain why buyers must be vigilant about inspections, paperwork, and setting expectations in writing with this or any dealership.

How to Escalate if Problems Occur

• Start with written requests: Email service/sales summaries with specific dates and requested resolution.
• Manufacturer support: If warranty-related, open a case with the RV manufacturer to pressure timely parts/approval.
• File a BBB complaint: Sometimes elicits a faster response: BBB search for M.B. Thomas RV Sales, Inc.
• Complain to the AG: If you suspect deceptive practices, file with the Missouri Attorney General: Missouri AG Consumer Complaints.
• Document safety issues: Report to NHTSA if defects pose a safety risk: Report a safety problem.

Final Assessment for RV Shoppers Considering M.B. Thomas RV Sales, Inc. (St. Louis)

This dealership operates as a privately owned business serving the St. Louis area. Public reviews and forum narratives capture a familiar pattern of RV dealership risks: surprises in final pricing, low-ball trades, title/paperwork frustrations, PDI misses that surface after the first trip, long repair timelines, and intermittent communication when backlogs grow. While some customers report satisfactory experiences and resolutions, the volume and seriousness of negative themes—particularly around inspections, delivery quality, and service timelines—warrants a highly cautious approach.

What should you do? Treat the inspection contingency as non-negotiable, demand a line-item out-the-door quote without add-ons, secure preapproved financing, and document every conversation and commitment in writing. Search multiple independent sources (YouTube, Reddit forums, BBB) and verify the most recent Google reviews by sorting from lowest rating first on the dealership’s page: M.B. Thomas RV Sales, Inc. – Google Reviews. Also, leverage independent guidance from veteran RVers such as Liz Amazing’s educational deep-dives to understand common pitfalls before you commit.

Bottom line: Given the risk patterns documented in public feedback about this location and the broader RV dealership landscape, we do not recommend proceeding without a third-party inspection and ironclad written terms. If the dealership is unwilling to meet these standards—and/or if low-star patterns remain unresolved—we recommend you consider alternative dealers with stronger verified service records.
