# Inspection and Evaluation for Eastvale, California > Structured in shop condition assessment on a lift, with moisture readings, systems testing and a written prioritized findings document. Source: https://ocrv.info/services/custom-fabrication-and-detailing/inspection-and-evaluation Inspection and evaluation is a structured in shop condition assessment of a recreational, commercial or specialty vehicle. The vehicle goes on a lift, moisture readings are taken through the sidewalls and roof, systems are operated and measured, and findings are issued as a written document with photographs and prioritized recommendations. ## Pricing Range $300 to $1,200. Labor band 2 to 6 hours. Performed in shop at 23281 La Palma Ave, Yorba Linda, CA 92887. Buying a used coach, deciding whether an aging one deserves investment, or planning a maintenance year for a fleet all require the same thing: an accurate picture of current condition. A walkthrough in a parking lot cannot provide that. Water intrusion hides inside walls, frame cracks hide under coating, and a generator that starts tells you nothing about whether it carries load. Finding those conditions requires a lift, instruments and time. This assessment is performed in shop at the Yorba Linda facility, never at a seller location, a storage yard or a driveway. The vehicle comes here, goes on the lift, and gets examined from underneath, from the roof and from inside with panels opened where access is required. That access is precisely what makes the difference between a report that describes the visible surface and one that describes actual condition. The output is a written document rather than a conversation. Moisture meter readings by location, photographs of every finding, system test results with actual numbers, and a prioritized list separating safety items from items that should be addressed soon from items worth monitoring. Buyers use it to negotiate. Owners use it to plan. Fleet managers use it to budget. All three benefit from findings stated with evidence attached. ## What brings this in - Considering purchase of a used coach or trailer - Unsure whether an aging unit is worth further investment - Planning a maintenance budget for a fleet - Suspected water intrusion with no visible source - Vehicle returning from long term storage - Preparing to sell and wanting condition documented - Previous repair work of unknown quality ## What Gets Examined and How The roof is walked or accessed from a platform, and every sealant bead around vents, air conditioners, skylights, antennas and the front and rear cap seams is inspected individually. Membrane condition, previous repairs, fastener corrosion and any soft areas underfoot get documented. Roof problems generate most of the expensive water damage found in coaches, so this portion of the assessment receives considerable attention rather than a glance from a ladder. Underneath, the vehicle is examined on a lift. Frame members, outriggers, crossmembers, suspension attachment points, holding tanks and their supports, plumbing runs, the underbelly enclosure and any previous repair work are all inspected directly. Corrosion, cracks, sagging supports and wet insulation are documented with photographs and location references so the owner can find each item again without a technician standing beside them. - Roof sealant beads inspected individually, not surveyed from a distance - Vehicle raised so frame and underbelly are examined directly - Moisture readings taken at a grid of sidewall and roof locations - Slide rooms operated through full travel with seals inspected - Every finding photographed with a location reference ## Systems Testing With Numbers Attached Appliances are operated rather than observed. The refrigerator runs on both propane and electric with cabinet temperature recorded over time. The water heater is fired and its recovery checked. The furnace is cycled through its full sequence. Air conditioners run to steady state with temperature split measured at the register. A generator is started and load tested rather than idled, because a set that runs and a set that carries two roof air units are different things. Electrical testing follows the same principle. House bank condition is assessed under load rather than by resting voltage. Converter output is measured at the bus. Shore power is verified on both legs with a thermal scan of the panel and transfer switch. The fresh water system is pressurized and held. Each result appears in the report as a figure, so a reader can compare it against expected values instead of reading a subjective judgment. ## Moisture Mapping and Structural Condition Water intrusion is the condition that most affects value and most often goes undetected. A meter is used at a grid of points across sidewalls, around every window and door, at the roof to wall transition, around slide openings, in the floor near plumbing fixtures and along the lower sidewall. High readings are recorded by location so the pattern is visible, because a cluster of readings tells a very different story than a single high point. Where readings indicate moisture, we look for the mechanism. A wet reading below a window points at the window seal. A pattern along the roof line points at a cap seam. Readings in a floor near a fixture point at plumbing. Delamination is checked by tapping and by looking down the sidewall in raking light, since a wall that has separated from its substrate shows a visible ripple long before it feels soft. - Grid of moisture readings recorded by location rather than sampled - High readings traced to a probable entry mechanism - Delamination checked by tapping and by raking light survey - Floor condition assessed around every plumbing fixture - Slide seal and opening condition inspected with the room extended ## The Report and How Owners Use It Findings are organized by priority rather than by location, because that is how decisions get made. Safety items come first: anything involving propane, combustion, structural integrity, braking components or electrical hazard. Then items requiring attention in the near term, typically active water intrusion or a condition that will worsen quickly. Then items worth monitoring, which are noted with what to watch for rather than presented as urgent work. Each item carries a photograph, a location, a description of what was observed and, where relevant, the measurement that supports it. Where a finding suggests repair work this shop performs, the applicable published price band is referenced so the owner can estimate the total picture. Nothing in the document commits the owner to anything, and many take it elsewhere or use it to negotiate a purchase price, which is a perfectly reasonable use of it. ## Frequently asked questions ### Can the assessment happen where the vehicle is currently parked? No. It is performed in shop at 23281 La Palma Ave in Yorba Linda, roughly twenty miles from Eastvale by way of SR-71 and SR-91. The value comes from the lift, the instruments and the access to open panels, none of which travel. A visual walkthrough in a driveway would miss the frame condition and underbelly findings that matter most. ### What does the evaluation cost? This service carries a published price band listed on the prices page, and the figure reflects the hours involved in a genuine assessment with the vehicle on a lift. It is a paid service rather than a courtesy walkthrough. Collision estimates for insurance work are handled separately and are complimentary, which is a different service with a different purpose. ### Can I use the report to negotiate on a used coach I am considering? Owners do that routinely and it is a sensible use of the document. The report describes observed conditions with photographs and measurements attached, which is far more persuasive in a negotiation than a general impression. There is no requirement to have any of the identified work performed here, and many buyers use the report purely to decide whether to proceed at all. ### How long does the assessment take? Plan on the vehicle being here most of a day for a thorough assessment, and longer on large coaches with multiple slides and extensive systems. The published hour range appears on the prices page. Systems testing accounts for much of the time, because appliances have to run long enough to reach steady state before their performance can be measured honestly. ### Do you evaluate commercial and municipal vehicles as well? Yes. Box trucks, utility trucks, shuttle buses, food trucks and mobile business vehicles all receive the same structured treatment adapted to their equipment. Fleet customers typically request evaluations across several units so that common failure patterns become visible, which supports planning repairs across the group rather than addressing each vehicle as an isolated case. --- OCRV Center. 23281 La Palma Ave, Yorba Linda, CA 92887.
