RV Structural Damage Assessment and Teardown Report

What the Assessment Includes

The assessment is a defined sequence, not a look and a guess. It starts with a full visual survey of the unit, inside and out, documenting the damage zone and every seam, fastener line, and sealant bead within reach of the impact. We record the model year, floor plan, chassis, and any prior repair we can identify, because a previously repaired area behaves differently and affects both the repair plan and the claim.

From there it moves through tap testing to find laminate separation, moisture mapping with a meter to find water intrusion, and laser measurement against factory reference points where structure may have moved. If the visible evidence points to hidden damage, we request authorization for partial teardown so we can actually look rather than speculate. Nothing gets removed without your approval and a stated hour estimate for that step.

The deliverable is a written report. Photographs organized by area, the moisture map with readings, the measurement sheet with tolerances, and a line item repair plan listing part numbers, labor operations, and hours at the applicable rate. That document is written to be read by an adjuster, which means it uses standard operation descriptions rather than shop shorthand. You get a copy regardless of whether you proceed with the repair.

• Full interior and exterior visual survey with damage zone documentation
• Tap testing across the damaged panel and surrounding area
• Moisture mapping with meter readings recorded by location
• Laser measurement against factory reference points where structure moved
• Partial teardown performed only with your written authorization
• Line item report with part numbers, operations, and hours

How the Fee Credit Works

Diagnostic labor bills at $285 per hour. If you authorize the repair we quote, those diagnostic hours come off the repair invoice as a credit. A two hour assessment at $570 that leads to an authorized $9,000 repair means you pay $9,000, not $9,570. The credit applies to the assessment hours specifically, and it applies when the repair is authorized at our shop. That is the whole mechanism and there is nothing buried in it.

There is also a $150 RV systems assessment, which is a separate and narrower check covering power, plumbing, propane, and slide operation. On a collision file it is usually run alongside the structural assessment, because systems damage in the impact zone is common and invisible from outside. That $150 is credited against an authorized repair on the same terms as the diagnostic hours.

If you decide not to proceed, you keep the report and you owe the diagnostic time. That is a fair trade and most owners see it that way once they hold the document. A written assessment with photographs, meter readings, and measurements is what a carrier acts on and what a second shop can quote against. It is a portable asset, not a fee for the privilege of getting an opinion.

Moisture Mapping and the Tap Test

The tap test is exactly what it sounds like and it is one of the most reliable diagnostic methods we have on a laminated wall. A sound laminated panel returns a sharp, consistent tone. A panel where the fiberglass has separated from the substrate returns a dull, hollow sound. We tap in a grid pattern across the damaged area and outward until the tone goes back to normal, then mark the boundary. That boundary is almost always significantly larger than the visible damage.

Moisture mapping runs in parallel with a pin type or pinless meter, taking readings on a grid across the interior wall surfaces, around window and door openings, along the floor edge, and in the compartment areas below. Each reading is logged by location. Elevated readings that trace a path back to a specific seam or fastener line tell you where water is entering, which is the difference between fixing the leak and repeatedly repairing the damage it caused.

Together these two methods define the actual repair boundary before anything is cut. A collision repair that stops at the visible damage on a wall with laminate separation extending twelve inches further will crack again along that boundary. Owners are often surprised how far the marked area extends past the dent. That surprise is exactly the value of the assessment, and it is the number that should drive the claim.

• Grid pattern tap testing outward until tone returns to normal
• Separation boundary marked and photographed before any cutting
• Meter readings logged by location across walls, openings, and floor edge
• Elevated readings traced back to the entry seam or fastener line
• Repair boundary set from test results, not from the visible dent
• Both results included in the report with photographs

Laser Measurement Against Factory Reference Points

When the damage pattern suggests structure moved, measurement replaces opinion. We level the unit on stands, establish a datum plane, and shoot the manufacturer specified reference points with a laser system. On a trailer that is axle centers, spring hanger locations, coupler position, and rail ends. On a motorhome chassis it is the control points the chassis maker publishes. Every reading is compared against the specification and recorded with its tolerance.

This is what separates a real assessment from a visual estimate. A rear corner impact on a long trailer can put a measurable twist at the tongue, and nothing about the appearance of the rear corner tells you that. Conversely, damage that looks alarming sometimes measures perfectly within tolerance, which turns what an owner feared was a frame job into skin work. Both outcomes save money, and only measurement produces either one.

The measurement sheet goes into the report with the tolerance for each point noted alongside the reading. Adjusters take that document seriously because it is verifiable and repeatable. If the repair proceeds, the same points get shot again after correction, and that post repair sheet becomes part of the closing documentation on the file. Anyone can claim a frame is straight. A sheet with numbers on it is a different kind of statement.

Partial Teardown Authorization and Why It Pays

There is a limit to what any inspection method reveals through a closed wall. When tap testing and moisture readings say something is wrong behind a panel, the only honest next step is to open it. We request written authorization for a defined teardown scope with an hour estimate before we remove anything, so you know what you are agreeing to and what it will cost before a single fastener comes out.

Typical partial teardown is removing interior wall panel in the damage zone, pulling a section of exterior trim or a fender skirt, or dropping a compartment liner to see the back side of the impact. Two to six hours of diagnostic time covers most of it. What comes back is the actual condition of the framing, the wiring, the plumbing runs, and the insulation, which is the information a repair plan and a claim both need.

The economics are straightforward. A $900 teardown that reveals crushed framing and wet substrate turns a $3,000 estimate into an accurate $11,000 estimate before you have committed to anything. Discovering that same damage after a shop has already started work turns into a supplement fight, a schedule slip, and sometimes an owner covering the gap. Paying to look first is the cheapest part of a large collision file.

Reading the Report Your Adjuster Gets

The report is organized the way a claim gets processed. Vehicle identification and condition first, then the damage description, then the diagnostic findings section containing tap test boundaries, moisture readings, and measurement results with photographs keyed to each. After that comes the repair plan as line items, each with an operation description, part number where applicable, quantity, and hours at the applicable rate.

Rates appear on the document explicitly. Body and paint at $210 per hour, mechanical at $260 per hour, diagnostic at $285 per hour, detail at $95 per hour, and paint supplies at $55 per paint hour. Parts show markup at 100 percent for items at or under $100 and 35 percent above that, and sales tax at 7.75 percent is applied to parts and materials only, never to labor. An adjuster can audit every line without calling to ask what something means.

What the report does not do is hide contingency in vague operations. If teardown is likely to reveal more, the report says so, names the specific areas of concern, and states what additional teardown would cost to resolve. Carriers respond much better to a document that identifies uncertainty up front than to a supplement that arrives three weeks later describing something nobody mentioned at intake.

• Vehicle identification, condition, and damage description up front
• Diagnostic findings with photographs keyed to each result
• Line items with operation, part number, quantity, and hours
• All labor rates and the paint supply rate stated on the document
• Parts markup and 7.75 percent tax on materials shown separately
• Areas of remaining uncertainty named with the cost to resolve them
