Community Research: Where to Find Unfiltered Owner Feedback

• Model-specific Facebook groups (via Google): Join multiple brand/model owner groups to see recurring issues and dealer service experiences. Try: Search model-specific Facebook RV owner groups.
• RV forums: Honest, searchable threads about warranty repairs, dealer delays, and DIY fixes often expose patterns you won’t get on a sales floor.
• YouTube owner reviews: Look for long-term reviews that explain what broke, what was covered, and how the dealership responded. Start with: RV consumer education by Liz Amazing.

Do This First: Arrange a Third-Party RV Inspection Before You Sign

A pre-purchase, independent inspection is the single most effective way to protect yourself. Many RV dealers (including those with average or mixed ratings) deliver coaches with unresolved defects that become your problem after the sale. Once they have your funds, you lose leverage and can be pushed to the back of the service line—some owners report missed vacations and months-long waits while their “new” RV sits in the shop.

• Hire a certified mobile RV inspector to check seals, roof, slides, appliances, electrical, plumbing, frame/axle condition, tires, brakes, LP systems, and moisture intrusion.
• Make your purchase contingent on a clean inspection report and a written “We Owe” list of fixes with due dates.
• If a dealer won’t allow a third-party inspection, walk. That refusal is a major red flag.

Observed Patterns in Consumer Complaints at Diederich’s RV Mart (West Coxsackie, NY)

Below are recurring themes reported by consumers on public platforms. We encourage readers to verify these themes by reviewing the most recent low-star reviews on the dealership’s Google page and searching the forums and links provided later in this report.

High-Pressure Sales and “Packages” You Don’t Need

Multiple buyers across the RV industry describe intense upselling during finance and delivery. While this is a common tactic at many dealerships, several reviewers for this location suggest similar patterns—add-on products presented as “must-have” protections or “dealer prep packages” that add hundreds or thousands to the out-the-door price.

• Extended service contracts with vague coverage and strict exclusions
• Paint/fabric protection, VIN etching, nitrogen tire fills, and “environmental packages”
• Services the manufacturer already includes (PDI, basic prep) repackaged as premium line items

Action steps:

• Ask for a full menu price list that itemizes every add-on. Decline what you don’t want or negotiate the price to zero.
• Secure outside financing before you shop so you can compare the dealer’s rate and avoid pressure to buy warranty products to “qualify” for financing.

For tactics to dodge costly add-ons, search the consumer-focused content on Liz Amazing’s YouTube channel.

Low-Ball Trade-In Valuations and Interest-Rate Markups

Several 1–2 star reviewers across dealer profiles nationally report that “great trade numbers” over the phone shrink on site, or that financing terms come with higher-than-expected rates. While we cannot confirm each individual case here, shoppers at this location have described trade-in value disappointments and finance surprises on public platforms.

• Rate markups: Dealers often add 1–3 percentage points to the lender’s buy rate.
• “Payment packing”: Monthly payment quoted without a detailed breakdown of every fee and product.

Action steps:

• Bring outside pre-approval from your credit union/bank.
• Request a written, all-in, out-the-door price (no surprises at signing).
• Get an independent trade-in appraisal to compare and create leverage.

Delayed Titles, Registration, and Paperwork Errors

Delays in paperwork can leave buyers with an RV they can’t legally use. Several low-star reviews for various RV dealers cite title holdups of weeks or months; on this dealership’s Google page, consumers have alleged similar issues that can disrupt camping plans.

• Demand timelines in writing for title and registration.
• Escalate to the New York DMV or the New York Attorney General’s Office if promised delivery dates are missed with no explanation.

Pre-Delivery Inspection (PDI) and Quality Control Problems

Complaints alleging that units are delivered with obvious issues—leaks, inoperable appliances, cosmetic damage, or missing parts—appear across the RV industry and are echoed in negative reviews for this location. When PDI is rushed or superficial, new owners discover defects only after taking delivery, when leverage is minimal.

• Don’t rush delivery day. Allocate several hours to test slides, water systems, AC/heat, fridge, stove/oven, LP leak checks, outlets, GFCIs, and roof/caulking.
• Do a moisture check and inspect for soft spots, stains, or musty odors.
• Video the walk-through and write down every defect. Require a signed We-Owe list with dates.

Service Delays, Backlogs, and Cancelled Trips

Low-star reviews across many RV dealers frequently mention months-long waits for appointments and parts. Negative reviews for Diederich’s RV Mart in West Coxsackie similarly describe long timelines that derail planned trips. Industry-wide parts shortages have improved in some categories, but service departments remain strained.

• Get realistic timelines in writing before leaving your RV for service.
• Ask if the shop will document and prioritize safety issues (LP leaks, brakes, electrical shorts) ahead of cosmetic items.
• If post-sale support appears non-responsive, document your timeline publicly for other shoppers.

Warranty Denials and “Manufacturer vs. Dealer” Finger-Pointing

A common pain point: the manufacturer blames the dealer, the dealer blames the manufacturer, and the owner is stranded in the middle. Some negative reviews for this location describe similar frustration.

• Magnuson-Moss Warranty Act may protect you if covered items are denied unreasonably. Learn more at the FTC: FTC Warranty Guidance.
• Keep dated, written records and file a formal claim with the manufacturer alongside the dealer’s work order.

Inexperienced Technicians and Poor Workmanship

RV service is complex: plumbing, electrical (12V and 120V), LP gas, slide mechanisms, and structural maintenance. Multiple reviewers in the broader RV market report incomplete or incorrect repairs that lead to repeat visits. Negative feedback for this location has also alleged workmanship issues ranging from leaks to appliance failures shortly after service.

• Insist on test results (LP pressure/soap test, electrical load checks, water system pressure tests) before paying.
• Examine seals and caulking, wire routing, and appliance operation in the lot before you leave.

“We’ll Fix It After the Sale” Promises and Misrepresented Features

Some reviewers across dealers report being told that minor issues would be corrected after delivery—only to discover the service queue is weeks or months long. A few negative reviews for this location also describe unkept delivery-day assurances or confusion about features/packages that were supposedly included.

• Do not accept verbal promises—get a signed due bill/We-Owe with timelines.
• Photograph the VIN and the exact unit you’re buying; confirm that the features match the listing.

Parts Ordering, Communication Gaps, and Escalation Challenges

Buyers repeatedly report frustration when promised updates never arrive. This can be particularly stressful if your camping season is short. While some service teams are responsive, negative reviews indicate inconsistent communication at this location.

• Ask for a weekly status email and a single point of contact.
• Request order numbers and ship ETAs for transparency.

Fees, Pricing Transparency, and Surprise Add-Ons

Unexpected fees—doc fees, prep fees, market adjustments—can inflate the real cost of the RV. Low-star reviews for numerous dealerships (including this one) commonly cite last-minute line items that weren’t disclosed during negotiations.

• Negotiate from an out-the-door price that includes tax, tag, title, and dealer fees.
• Ask for a signed purchase order before you travel to the store.

Safety and Recall Considerations: What Defects Mean for Real Families

Several problem types reported by consumers pose real safety risks:

• Water leaks and mold: Roof and slide leaks lead to rot, soft floors, and health concerns for children and immunocompromised people.
• LP gas leaks: If LP systems aren’t leak-tested, owners face fire and explosion hazards. Always verify a proper LP system test before pickup.
• Electrical issues: Miswired outlets, failed GFCIs, and converter/inverter problems can cause shocks or fires.
• Axle, brake, and tire problems: Poor alignment or under-spec’d components contribute to blowouts and loss of control.

Before purchase and after any service, run your VIN for open recalls and check the brand’s recall history at the NHTSA Recall Database. You can also start with a dealership-specific query here (then refine by your actual RV brand/model): NHTSA recall search placeholder.

If you’ve experienced a safety-critical defect tied to repairs or delivery at this location, post the details to warn other families.

Legal and Regulatory Warnings

When dealers fail to deliver promised services or paperwork—or misrepresent warranties—consumers may have legal remedies:

• Deceptive business practices (NY GBL § 349): New York prohibits deceptive acts or practices in commerce. Document misrepresentations, missing paperwork, and undelivered promises. File with the NY Attorney General.
• Magnuson-Moss Warranty Act: If written warranties are not honored, you may have federal protections. See the FTC’s warranty guide.
• Truth in Lending Act (TILA) and FTC Holder Rule: Finance paperwork must accurately disclose terms. The Holder Rule can allow claims against the finance company for seller misconduct. Learn more from the FTC.
• Title and registration delays: If a dealer fails to timely transfer title, report to the New York DMV and the AG’s office.
• Safety defects: File complaints with NHTSA if a repair or unit defect poses a hazard.

Consider sending a formal demand letter, then filing complaints with the NY Attorney General and relevant federal agencies if unresolved within a reasonable timeframe. If you financed, notify the lender in writing, citing the FTC Holder Rule, and request they pause payment obligations while the dispute is investigated.

How to Protect Yourself If You Shop Here

• Get it in writing: Every promise, every repair, every freebie—due-dated in a signed We-Owe form.
• Independent PDI: Hire your own inspector before final payment. Start here: Find an RV inspector near me.
• Out-the-door (OTD) number only: No verbal quotes. Demand a signed purchase order with all fees.
• Refuse unnecessary add-ons: Extended warranties and protection packages are often high-margin. Buy later if you want, after independent research.
• Check recalls and TSBs by VIN on NHTSA and the brand site before delivery.
• Document everything: Video your PDI and every conversation. Follow up by email for a paper trail.
• Escalate smartly: If issues stall, involve the manufacturer, NY AG, and your lender. Consider mediation or small claims where appropriate.

Acknowledging Improvements or Resolutions

It is fair to note that some buyers report satisfactory purchases and responsive staff at many independent dealers, and occasional positive updates also appear in public reviews for this store. Parts availability has improved in certain categories since the pandemic-era supply chain crunch, and some service cases do get resolved with persistence and documented communication. Still, the recurring patterns in low-star feedback for Diederich’s RV Mart in West Coxsackie—especially around PDI quality, paperwork delays, communication, and add-on pressure—are significant enough that shoppers should proceed with elevated caution, extra documentation, and an independent inspection.

What Real Owners Say: How to Read the Reviews Productively

To make the most of consumer feedback, go directly to the source. On the dealership’s Google profile, click “Sort by Lowest Rating.” You’ll often see themes like delays in paperwork, quality control misses at delivery, slow or uneven service communication, and pressure to purchase add-on products.

• Consider an independent inspection to document problems for warranty or legal escalation. Search: RV Inspectors near me.

Balanced Perspective: Independent Dealer, Local Reputation, and Buyer Responsibility

Diederich’s RV Mart LLC is not a national chain; as a private, single-location operation, reputation is largely built on local word-of-mouth, online reviews, and repeat customers. That can be a strength when leadership prioritizes customer care. However, based on recurring negative themes observable on public platforms, shoppers should approach this location with the same skepticism and due diligence they would bring to any large RV purchase: independent inspections, written commitments, and willingness to walk if expectations aren’t met.

Bottom Line: Risk, Accountability, and a Practical Buying Strategy

Buying an RV is a major financial and lifestyle decision. A dealer’s service capacity, transparency, and follow-through matter more than any sales pitch. For Diederich’s RV Mart in West Coxsackie, NY, public complaints highlight concerns over paperwork delays, PDI quality, service timelines, communication gaps, and upselling—issues that can cost owners time, money, and missed camping seasons. The best defense is a professional inspection before signing, a detailed We-Owe list with dates, and refusal to pay for unnecessary add-ons.

For additional education on navigating dealer experiences, you can search investigative content by consumer advocates like Liz Amazing to build your personal checklist and negotiation plan.

Recommendation: Given the consistent pattern of complaints visible on the dealership’s Google reviews and across RV owner communities, we do not recommend purchasing from Diederich’s RV Mart LLC (West Coxsackie, NY) without a third-party inspection, airtight written commitments, and full pricing transparency. If these protections aren’t possible—or if you encounter resistance to an outside inspection—strongly consider shopping other RV dealerships.
