About Dewayne Marion & HD-RV Inspections Texas
Aerospace Precision Meets Texas RV Inspection
HD-RV LLC was founded by Dewayne and Halina Marion on a simple principle borrowed from a combined 50 years in aerospace quality work: a defect found before delivery costs pennies — a defect found after costs everything. We bring zero-defect aerospace discipline to the highly variable world of recreational vehicle manufacturing, protecting buyers across San Antonio, Austin, Houston, and the entire state of Texas from the catastrophic financial risk of an uninspected purchase.
Who Inspects Your RV — And Why It Matters
Every HD-RV inspection is performed personally by the founders. No subcontractors, no rotating technicians, no "whoever was available that day." When you hire HD-RV, you hire Dewayne and Halina Marion — a husband-and-wife team with a combined 50 years of aerospace quality experience working side by side on every inspection.
From Aerospace Tolerances to RV Realities
Before founding HD-RV LLC, Dewayne and Halina each spent over two decades in the aerospace industry, where parts are inspected to thousandths of an inch and a single overlooked flaw can ground a fleet. That world operates on documented protocols, traceable evidence, and a non-negotiable standard: find it before it flies. Two trained sets of aerospace eyes on the same coach is not redundancy — it's how serious quality work has always been done.
The recreational vehicle industry, by contrast, operates on assembly-line speed with build quality that varies dramatically between units — even between two coaches that rolled off the line on the same shift. Sealant gaps, misrouted wiring, undersized propane runs, and skipped torque specs are not rare exceptions in modern RVs. They are predictable findings. The difference between a buyer who gets blindsided and a buyer who walks away protected is whoever inspected the unit before the check was signed.
A Husband-and-Wife Inspection Team
HD-RV is a true family-run operation. Dewayne and Halina work every inspection together, dividing the coach into systems and cross-checking each other's findings the same way aerospace inspection teams have always operated. Halina brings 25 years of her own aerospace, quality-driven experience to every job — same documentation rigor, same methodical pace, same refusal to skip a step. You're not getting one inspector — you're getting a two-inspector team for the price of one inspection.
A Lifetime Around Vehicles
Dewayne's mechanical fluency didn't start in a hangar. It started under the hood of a 1976 Chevy Nova and inside a vintage Scout camper — vehicles he learned to maintain, troubleshoot, and rebuild long before he ever wrote an inspection report. That early hands-on experience with carburetors, drum brakes, generator wiring, and canvas-pop seal failures gave him an intuitive understanding of how older systems fail — and how modern RV systems often replicate the same failure modes despite newer materials.
The combination is unusual in this industry: NRVIA-certified inspection paired with deep aerospace methodology, a lifetime of practical mechanical work, and zero financial relationship to any dealership, manufacturer, or repair shop. That last point is non-negotiable. HD-RV inspects on behalf of the buyer — and only the buyer.
Why Does an Aerospace Background Matter for Your RV?
Aerospace work trains you to look for what the assembly process is most likely to miss — not what's most obvious. It teaches you to assume the unit will fail, then methodically prove it won't. Applied to a 40-foot diesel pusher or a brand-new travel trailer, that mindset surfaces issues a standard "walk-through" never catches: deteriorating slide seal condition, compromised roof sealant, AC condensate paths leading into wall cavities, or appliances that power on but aren't actually working as intended. Two aerospace-trained inspectors working together catch what one would miss alone.
How Does HD-RV Inspect An RV?
We don't "look at" RVs. We diagnose them. Every inspection follows a structured, NRVIA-aligned protocol with documented evidence at every stage — the same evidence-first approach used in aviation maintenance, applied to the systems that determine whether your RV is actually safe, livable, and worth its asking price.
"Blood Test" Fluid Analysis Optional Add-On
Available as an optional add-on service at additional cost. For motorized coaches and onboard generators, we pull samples from the engine, transmission, and generator and submit them for laboratory fluid analysis. Like blood work for a patient, lab results reveal internal wear metals, coolant intrusion, fuel dilution, and oxidation — failures invisible to a visual inspection or a test drive.
Please note: Fluid analysis requires additional turnaround time beyond the main inspection report. Samples must be mailed to the laboratory, analyzed, and results returned via email — typically adding several business days to final delivery.
Manometer Propane Testing When Accessible
Performed when the RV provides a way to access the propane system — either through an external test port or via a stovetop that allows access. When accessible, the system is tested under pressure with a calibrated manometer to detect leaks measured in fractions of a PSI. A "passes the soap test" check is not a propane test. A timed pressure-drop reading on a manometer is the only standard that proves the system is sealed.
Electrical Load & Polarity Verification
Shore power, inverter, converter, generator transfer, and 12V DC systems are tested under live load — not just for continuity. We verify polarity, ground integrity, voltage drop under appliance load, and proper transfer switch operation across all power sources.
Roof, Seal & Envelope Inspection
Every accessible inch of the roof is walked, photographed, and probed. Sealants are evaluated for adhesion, cracking, and remaining service life. Slide seals, window flanges, and body seams are documented systematically because moisture intrusion is the #1 destroyer of RV value in Texas.
Appliance & System Function
Every appliance — refrigerator (in both modes), furnace, water heater, AC units, washer/dryer, awnings, slides, leveling jacks — is operated through full cycles. We document temperatures, run times, error codes, and any performance deltas from manufacturer spec.
Photographic Evidence Report
You receive a written report with 75 to 100+ high-resolution photos, organized by system, with each finding tied to a specific image. Reports are typically delivered within 24 hours so you can act on contingencies, negotiate repairs, or walk away — before deadlines force a bad decision.
The Mission: Quantifying What You're Actually Buying
Every used RV carries inherited risk across three independent failure domains. Our protocols exist to surface, document, and quantify each one before you sign:
Electrical risk (shore power faults, inverter failure, ground issues). Mechanical risk (engine, transmission, generator, slides, jacks, brakes). Environmental risk (water intrusion, UV degradation, sealant failure, frame corrosion). A walk-around tour catches none of these. A documented inspection catches all three.
Why Does the Texas Climate Demand a Specialized Inspection?
A pre-purchase RV inspection in Texas is not the same job as one performed in Oregon or Michigan. The Texas climate accelerates failure modes that inspectors in cooler, wetter regions often deprioritize. Ignoring this is how out-of-state buyers end up with a "great-condition" RV that develops a $14,000 problem in its first Texas summer.
Intense UV Exposure
Texas UV index regularly exceeds Northern-state peaks for months at a time. UV is the primary degrader of roof membranes, sealants, decals, awning fabrics, and tire sidewalls. We evaluate sealant elasticity and membrane condition against a Texas-service-life standard, not a national average.
San Antonio & South Texas Heat
Sustained 100°F+ ambient temperatures stress every cooling system on board: engine cooling, transmission cooling, generator cooling, refrigerator condensers, and rooftop AC units. We test cooling capacity under realistic thermal load, not just "does it turn on."
Hill Country Terrain
Texas Hill Country RV use means sustained grades, heat-soaked brake systems, and chassis stress that flat-state operation never imposes. Brake life, transmission fluid condition, suspension components, and weight distribution all require evaluation against this real-world duty cycle.
Sudden Storm & Hail Exposure
Central and South Texas see rapid storm cycles, hail, and high-wind events. Past damage is often cosmetically repaired but leaves compromised seals, dimpled aluminum, and stress-cracked fiberglass. We document hail history evidence the seller may not disclose.
Humidity Swings
Coastal humidity and dry-region exposure within the same trip cycle materials between expansion and contraction. This is the failure mode that breaks slide seals and window gaskets faster than steady-climate use ever would.
Long Storage Periods
Many Texas RVs sit for months in direct sun. We inspect for the specific failure signatures of long static exposure: tire flat-spotting, fluid stratification, rodent intrusion, and seal degradation that only shows once the unit moves.
Where Does HD-RV Provide Mobile RV Inspection Service?
HD-RV is a true mobile RV inspection service. We come to the dealership, the private seller's driveway, the consignment lot, or the storage facility — anywhere the unit is, anywhere in Central and South Texas, with extended service into Houston and major metros.
Are You Buying an RV From Out of State?
This is the scenario HD-RV was built for. When you can't physically inspect a unit before wiring funds, your inspector becomes your eyes, your hands, and your negotiating leverage. Our 75–100+ photo reports are specifically structured for remote buyers: every system, every concern, every condition note tied to documented imagery — delivered within 24 hours so you can make a defensible decision before your purchase deadline expires.
We routinely inspect units for buyers in California, Florida, Colorado, the Pacific Northwest, and across the country who have located the right RV in Texas but cannot fly in to evaluate it themselves. Out-of-state buyer specialist status is not a marketing claim — it's the core of our practice.
What Standards Hold HD-RV Accountable?
Anyone can call themselves an "RV inspector." Very few operate under a third-party certifying body, a published code of ethics, and the documentation requirements that make an inspection legally defensible. HD-RV does.
Protect Your Purchase Before You Sign
Whether you're across town in San Antonio or across the country waiting on a Texas listing, HD-RV gives you the inspection report a smart buyer wouldn't close without.
