What pre-authorization actually is
Pre-authorization (also called prior approval) is a manufacturer agreeing, in writing, that a defect is theirs and that they will pay for a defined repair. It usually comes back with an authorization number, an approved labor time and sometimes approved parts. That number is what you bill against.
Without it, a completed repair is a request for reimbursement on work the manufacturer never agreed to. The reviewer can question the diagnosis, the method, the parts or the time — and the unit is already fixed, so there is nothing left to inspect. The shop has spent the labor; the only open question is how much of it comes back.
From the manufacturer’s side, a claim is a commitment of money on a unit they cannot see. Approving the repair before it happens lets them steer it: choose repair over replacement, route a component to its supplier, send a field representative, ship a part from the factory, or cap the time at their flat rate.
That is why we write every line as issue detected plus authorization requested — “Request authorization to replace awning motor (P/N …)” — and never as completed work. Past-tense lines read as repairs done without permission, and that alone can sink them. The same discipline applies on arrival (DAF), PDI and warranty claims alike.
What triggers the need for prior approval
Thresholds and rules vary by manufacturer and change over time. Read the current warranty policy manual for each brand you sell — these are the usual categories.
Labor above a set threshold
Many manufacturers require approval once a line or a claim passes a certain number of hours or dollars. The threshold differs between brands, so keep a current reference for each one your service desk handles.
Structural, water and slide-out repairs
Frame, floor, wall, roof and slide-out work is high-dollar and hard to verify after the fact. Expect these to need approval almost regardless of the hours.
Major component replacement
Replacing rather than repairing an expensive component — a slide mechanism, a leveling system, an appliance — often needs approval, and the manufacturer may route it to the component supplier instead.
Sublet and outside work
Glass, fiberglass, paint, frame or mobile work sent to an outside shop usually needs the sublet approved, with the outside estimate attached.
Repeat repairs and unusual requests
A second attempt on the same complaint, or a repair method outside the norm, is a natural point for the manufacturer to want a say before more money goes in.
Building a request that gets approved
The reviewer approves what they can see and understand. Give them all of it in the first submission.
VIN tag and unit details first
VIN tag photo, model, in-service date and current mileage or hours where relevant. No VIN, no claim — and nothing else in the request is anchored without it.
Issue detected, in Complaint and Cause
What the technician found, where, and why it is a factory defect. Specific and factual: “corner seal not bonded at upper rear corner of bedroom slide-out,” not “slide leaks.”
Repair requested, in the Correction
The steps the repair requires and the verification at the end, written as a request. Simple issues get a short Correction; complex ones get the full narrative.
Photos for every line
A wide shot to locate the issue, a close-up to show the defect, and any readings or test results in frame. Each line carries its own photos so the reviewer never has to hunt.
The estimate: labor by step, parts by number
Flat-rate time where one exists; a step-by-step breakdown where the job runs beyond it or no flat rate applies. Parts with part numbers and quantities. A bare number is easy to cut; a justified one is hard to argue with.
Partial authorizations: read before you wrench
An approval is not always a yes to everything. The manufacturer may approve the repair but cut the labor, approve some lines and deny others, approve a repair instead of the replacement you asked for, or require a part to be returned or shipped from the factory.
Read the response line by line before the technician starts. If the approved time will not cover the job, respond with the step breakdown and photos and ask for the difference now — not after the hours are spent. If a line is denied, decide with the customer before the work proceeds whether it becomes customer-pay, goodwill, or a resubmission with more evidence.
Supplemental requests when you find more
Teardown reveals things. A wall opened for one leak shows wet framing past the original scope; a slide removed for a seal exposes a damaged floor. That additional work is a new request, not an extension of the old one.
Stop at the point of discovery. Photograph the new damage in place, explain why it could not be seen before the work began, list the added steps, time and parts, and submit a supplemental against the original authorization. Wait for the supplemental approval before continuing. Overage rolled into the original line without approval is the first thing a reviewer cuts.
Track every authorization number at the line level, not the claim level. One claim can carry an approved line, a cut line, a denied line and a pending supplemental — and the payment you receive will be reconciled against each of them separately. If the repair order, the claim and the payment do not all point to the same authorization number per line, short pays go unnoticed.
Customer-safety emergencies
Sometimes a unit cannot wait: a propane leak, a brake or hitch failure, an electrical fault, a slide that will not retract on a customer who has to travel. Safety comes first. Make the unit safe and contact the manufacturer through their warranty or after-hours channel as soon as you can — many have a process for exactly this, and your dealer agreement or warranty manual is where to find it.
Document everything as if the reviewer will read it cold: photos before anything is touched, the time you detected the issue, who you contacted at the manufacturer and when, what you were told, and why the repair could not wait. Do only what is needed to make the unit safe, keep the failed parts, and submit the request with the full record. A well-documented emergency is a very different claim from a repair that simply skipped the step.

RV warranty pre-authorization — FAQ
What is warranty pre-authorization for an RV dealer?
It is the manufacturer’s approval of a specific warranty repair, usually with an authorization number and an approved labor time, given before the dealer does the work. It confirms the manufacturer will pay for that defined repair.
When does an RV warranty repair need prior approval?
It depends on the manufacturer. Common triggers are labor above a set threshold, structural, water and slide-out repairs, major component replacements, sublet work and repeat repairs. Check each manufacturer’s current warranty policy manual for its exact rules.
What happens if I do the repair before getting authorization?
The claim becomes a request to be reimbursed for work the manufacturer never approved. It may be paid, cut or denied, and with the repair already done, there is little left to support it. Outside of documented safety emergencies, ask first.
Where do I put the warranty authorization number?
On the claim line it applies to, and on the matching repair order line in your shop system. Track it per line so payments can be reconciled against exactly what was approved.
What if we find more damage after the repair is authorized?
Pause the work, photograph the new damage in place, and submit a supplemental request tied to the original authorization with the added steps, time and parts. Continue once the supplemental is approved.
What if the manufacturer only approves part of the labor?
Respond before the work starts with a step-by-step labor breakdown and photos that justify the difference. Once the hours are spent, the leverage is gone.
