# OEM Parts Compared With Aftermarket on an RV Claim

> A carrier may specify a non original part only if it is **equal in kind, quality, fit and performance**, and must disclose it in writing. On RVs that test **fails on bonded panels and molded caps**.

## Will my insurance carrier pay for OEM parts on an RV repair?

Sometimes. A carrier may write an estimate line for an aftermarket or used part where an equivalent exists. On the RV work we do in Yorba Linda, molded caps, bonded sidewall skins, curved glass and slide rails usually have no equivalent, so those lines get corrected to OEM with measurements attached.

- Four categories appear on estimates: OEM, OE supplier, aftermarket, and used
- A non original crash part must be disclosed in writing on the estimate
- Aftermarket trim and lighting are usually fine on an RV
- Bonded panels and drive rails almost never have a working equivalent

### Key facts

| Item | Value |
| --- | --- |
| Parts markup | 100 percent at or under $100, 35 percent over $100 (Applied at the counter on every category, including used) |
| Sales tax | 7.75 percent (On parts and materials. Labor is not taxed) |
| Special order parts | Full non refundable deposit at order (Molded caps and tooled panels are order only) |
| Written repair estimate | $150 (Credited in full against an authorized repair) |
| Where equivalents do not exist | Molded caps, bonded skins, Schwintek rails, curved glass (The four lines we correct most often) |

The parts invoice is where most RV claim arguments actually start. A carrier estimating system prints a line for a replacement panel, prices it against whatever its parts database holds, and the number reads as reasonable. Then the part arrives in a crate at La Palma Avenue, gets offered up to the opening, and sits a quarter inch proud of the adjacent surface with a radius that does not follow the coach. Somebody now has to decide who pays for the part that will actually work, and that decision is easier to win before the crate is opened.

Parts sourcing on a claim is a separate subject from coverage for equipment you added to the unit yourself. This page is only about where a replacement component comes from and whether it will function once installed. Limits and valuation for a custom build belong to the added equipment page. The four categories below are the ones that appear on an estimate line, and knowing which category a line was written in tells you most of what you need to know about how the repair is going to go.

## The four parts categories that appear on an estimate

OEM means the component came from the coach manufacturer or the parts arm that supports it, in that builder's packaging, at that builder's price. OE supplier equivalent means the identical component bought from the vendor who supplied the builder in the first place, in that vendor's own packaging, which usually costs less and is just as correct. Aftermarket means a third party made something intended to approximate the original. Used or recycled means it was pulled off a dismantled donor unit and sold as removed.

On automobiles those four categories are roughly interchangeable across a huge catalogue of certified parts. On RVs they are not. The recreational vehicle industry never built a broad aftermarket for structural body components, because the volumes do not support tooling. That is why an RV estimate tends to sort cleanly: the small stuff has real alternatives, the large bonded and molded stuff has one source or no source, and the middle ground is thinner than an adjuster working from an automotive database expects.

**The four parts categories on an RV estimate line**

| Category | What it is | Where it works on an RV | Where it fails |
| --- | --- | --- | --- |
| OEM | Bought from the coach builder or its parts arm | Molded caps, laminated sidewall skins, curved glass, slide rails | Nothing except cost and lead time |
| OE supplier equivalent | The same component from the vendor who supplied the builder | Lippert, Dometic, Carefree, Furrion and Dexter items | When the builder specified a variant the vendor no longer catalogues |
| Aftermarket | A third party approximation of the original | Trim, marker lights, entry steps, bumper covers, fasteners | Bonded panels, structural skins, sync sensitive drive parts |
| Used or recycled | Removed from a dismantled donor unit | Curved glass, cooling units, cabinet doors, obsolete moldings | Anything whose internal condition cannot be verified before install |

## When a carrier may specify a non original part

California does not leave this to preference. The Fair Claims Settlement Practices Regulations at 10 CCR 2695 set out what an insurer may require, and the substance of the rule is that a non original replacement crash part has to be at least equal to the original in kind, quality, safety, fit and performance, and that its use has to be disclosed in writing on the estimate. Separately, the Business and Professions Code requires aftermarket crash parts to carry the maker identification, so what was actually installed is traceable afterward.

That rule was written with automobiles in mind, and it is the reason RV files generate so much friction. The disclosure obligation is easy to satisfy. The equal in fit and performance test is the hard part, because for a vacuum bonded sidewall there is nothing to compare against. When a line reads aftermarket on a component that has no certified equivalent, the correct response is not an argument about brand loyalty. It is a written statement of what the substitute would fail to do, with a measurement attached.

> **insurance:** Ask your adjuster to put the parts specification in writing early. A file that says non original where available reads very differently once the shop demonstrates that nothing is available.

## Where a non original panel will not fit or bond on an RV

Start with a molded fiberglass front cap. That cap was pulled from a mold cut for one model over a handful of years, and the mold either exists at the builder or it does not exist anywhere. There is no third party making a copy, because the tooling cost would have to be recovered over a few hundred units. When a cap line comes back priced against an automotive style aftermarket assumption, the honest answer is that the assumption has no product behind it.

Next is the laminated wall panel. A vacuum bonded sidewall is a sandwich, and the substrate matters more than the skin. A panel built over Azdel behaves differently under adhesive than one built over lauan decking, and a filon skin laminated to the wrong substrate will not develop a reliable bond line no matter how carefully it is rolled. That is a repair that looks correct at delivery and delaminates in the second summer, which is why the substrate gets identified before anything is ordered.

Then there are the parts that have to match a number rather than a shape. A Lippert Schwintek rail has to match the gear pack tooth count or the room never runs in sync. Curved Hehr and Kinro glass is formed to a radius no flat glass shop can produce. Carefree and Solera awning fabric comes out of dye lots, so a replacement panel that is technically the right pattern can still read as a different color across a fifty foot flank. A Furrion camera bracket has to hold the original sensor geometry or the display is aimed at the ground.

## Discontinued parts, and what happens when nothing exists

A meaningful share of the coaches on Southern California roads were built by companies that no longer exist, or by brands whose tooling was scrapped in a consolidation. When a cap, a compartment door or a one piece rear wall for one of those units is genuinely gone, the file has three honest paths. Fabricate a replacement from scratch. Source a serviceable original from a dismantled donor. Or accept that the repair number has climbed far enough that the value comparison changes.

Fabrication is real work and it bills as real work. Laying up a replacement cap section, fairing it to the adjacent surface and matching a decade old finish is body and paint labor at $210 per hour with paint supplies at $55 per paint hour, and it adds calendar days that a catalogue part would not. Carriers approve it routinely once the alternative is documented, because the alternative is a larger settlement. What stalls those files is a shop that says unavailable without saying what unavailable was verified against.

## Used and reconditioned assemblies, and when they are the right answer

Used parts have a bad reputation they do not entirely deserve. For some components a good original from a donor unit is better than anything else obtainable. Curved glass is the clearest case. Obsolete exterior moldings, cabinet doors in a discontinued finish and compartment latches are close behind. On those items the condition is fully visible before installation, so the risk is one you can actually inspect away.

Reconditioned Dometic and Norcold cooling units sit in a different category, and owners should understand the tradeoff. A reconditioned unit is a sealed system somebody else rebuilt, and its internal condition is a claim rather than an observation. We will install one when the owner and the carrier both want it and the file says so plainly, and we will say in writing that the condition was not verifiable at install. What we will not do is put a used part into a structural or a load path position, because a hidden crack in a donor component is not something an inspection finds.

## How the disagreement gets documented

Nothing about a parts dispute is won by phone. It is won by a file that shows the substitute failing. When a non original part is specified and it does not work, the part gets photographed in position against the opening, the gap gets measured at the same points on both sides, and the substrate gets identified and recorded. That package goes back with a single line stating what the part does not do. Adjusters at Progressive, GEICO, State Farm, Mercury and Foremost all move faster on a measurement than on an opinion.

If the carrier holds its position after the documentation is in, the disagreement stops being technical and becomes a policy question. Most policies contain an appraisal clause for exactly this, and the California Department of Insurance is where a complaint about handling gets raised. Your declarations page decides what your policy actually promises about parts, and that page is worth reading before the conversation rather than during it.

## What parts cost at our counter

Our parts pricing is posted and it does not change based on who is paying. A part at $100 or less carries 100 percent markup. A part over $100 carries 35 percent. Sales tax at 7.75 percent applies to parts and materials, and labor is not taxed, which is why the tax line on an RV invoice is often smaller than owners expect on a job that is mostly hours.

Special order parts require a full non refundable deposit at the time the order is placed. That is not a preference, it is what the supply chain demands: a molded cap or a tooled panel is built or pulled for one unit and cannot be returned to stock. On authorized repairs over $2,000 there is a 50 percent deposit at authorization, and over $10,000 an additional 25 percent when parts arrive. When a carrier is billed directly, those deposits are handled inside the claim rather than out of your pocket.

> **price:** A carrier that approves an aftermarket line at a lower price is approving a part, not a discount on labor. If the substitute has to be removed and the correct part installed, the removal hours become a supplement.

## Questions and answers

### Can my carrier require an aftermarket sidewall skin on an RV claim?

It can specify one, but under the Fair Claims Settlement Practices Regulations the substitute has to be equal in kind, quality, safety, fit and performance, and the use has to be disclosed in writing. On a vacuum bonded sidewall there is rarely a substitute that meets that test, so the line usually gets corrected once the substrate is identified and recorded.

### Why will a non original panel not bond to a vacuum bonded sidewall?

Because the bond depends on the substrate behind the skin, not the skin itself. A panel laid up over Azdel takes adhesive differently than one built over lauan decking. Put a filon skin on the wrong substrate and the bond line never fully develops, so the repair looks correct at delivery and starts delaminating within a season or two.

### What happens on a claim when a molded fiberglass cap is discontinued?

The file goes one of three ways: fabricate a replacement section, source a serviceable original from a dismantled donor unit, or accept that the repair number has moved far enough to change the value comparison. Fabrication bills as body and paint labor at $210 per hour and adds calendar days, and carriers approve it once unavailability is documented.

### Does a Schwintek rail have to match the original gear pack tooth count?

Yes. The rail and the gear pack are a meshed pair, and a mismatched tooth count means the two sides of the room never travel at the same rate. A racked room chews wiper seals and cracks interior trim, so a rail substitution that saves money on the parts line reliably creates a larger mechanical file later.

### Will a carrier pay for OEM Carefree fabric to match a dye lot?

Often, once the mismatch is shown rather than described. Carefree and Solera fabric is produced in dye lots, so a correct pattern can still read as a different shade across a long flank in daylight. A side by side photograph of the new panel against the original under the same light is what moves that line.

### How is an OEM versus aftermarket parts disagreement put in writing?

The substitute is photographed in position against the opening, the gap is measured at matching points on both sides, and the substrate is identified in the file. One sentence states what the part fails to do. If the carrier holds its position after that, most policies contain an appraisal clause and the Department of Insurance handles complaints about handling.

### What deposit applies to a special order RV part at your counter?

Special order parts require a full non refundable deposit when the order is placed, because a molded cap or a tooled panel is produced for one unit and cannot go back to stock. Parts at or under $100 carry 100 percent markup, parts over $100 carry 35 percent, and 7.75 percent tax applies to parts and materials.
