RV repair technicians and shop owners fix the living systems and the chassis of motorhomes, travel trailers, fifth wheels, and campers. Invoices usually cover diagnostic time, labor on appliances, plumbing, electrical, roofs, slide-outs, and awnings, plus parts and shop supplies. Many techs work solo from a mobile service truck, while others run a small shop with a few bays.

Most RV repair is billed hourly at a shop or mobile labor rate, with parts added at a markup. Many shops charge a diagnostic fee, often one hour, that is either separate or credited toward the repair if the customer approves it. Mobile service adds a trip charge or mileage on top of labor. Some jobs are priced flat or by book time, such as roof resealing, awning replacement, or winterization, where the scope is predictable. Larger work like water damage repair, fiberglass or roof replacement, or slide-out rebuilds is quoted as a project with a deposit. Warranty and insurance work is billed to the third party at their allowed labor rate and book times, which are often lower than retail. Parts are marked up to cover sourcing, shipping, and warranty on the part, and shop supplies are usually a small percentage or flat line.

RV parts vary widely by model year and chassis, and the record ties the work to the correct unit if a warranty or insurance claim comes up.
Writing the original complaint and your diagnosis shows why the work was needed, and it supports warranty and insurance reimbursement.
Customers dispute lump-sum labor more than itemized labor, and third-party payers often require line-by-line book time or actual hours.
Part numbers help with future repairs, returns, and manufacturer warranty claims.
Drive time is a real cost, and showing it as its own line prevents arguments about the hourly total.
Propane fittings, sealants, coolant, and old batteries cost money. Listing them separately keeps them from looking like padding.
It documents the customer approved the work and any additions, which protects you if the final bill is higher than the first quote.
Payment is usually due on completion, especially for mobile work where the customer may leave the area soon after. Many shops require a deposit for parts orders, commonly 50 percent or the full cost of special-order parts, and a deposit on larger projects. Shops that hold a unit can charge storage after a stated number of days past completion, which should be in writing. Warranty and extended-service-contract work is paid by the administrator, typically net 30 or longer, with the customer paying any deductible at pickup. Accept cards, ACH, and checks, and consider a fee or discount to cover card costs where your state allows it. Late fees of 1.5 percent per month are common, but check your state rules, and note that some states have mechanic's lien rules that let you hold a unit until you are paid.
RV problems often uncover more: water damage behind a leak, a failed slide seal, rotted subfloor. Stop, document with photos, and get written or texted approval before you continue, then add it as a change order.
Charge diagnostic time as its own line. Customers who decline the repair still owe for your time, and those who approve may have it credited, which you can state on the estimate.
Set a markup policy, such as a percentage that scales down on expensive items, and apply it every time. Include freight and sales tax where it applies in your state.
For manufacturer or extended-warranty jobs, record the claim number, the authorized labor hours, and the failure code. Missing details are the most common reason claims are rejected or delayed.
Put a storage policy on the intake form and invoice. Units that sit waiting for parts or payment take up bay or lot space you could use for paying work.
Yes. Diagnostic time is labor. Tell the customer the fee up front and put it in the estimate. Many techs credit the fee toward the repair if the customer approves the work.
It depends on the state. In many states, parts are taxable and labor is not, while others tax both or neither. Check with your state revenue department or an accountant, and show tax on its own line.
In many states a repair shop can keep possession of a vehicle until the bill for authorized work is paid, under a mechanic's or possessory lien. Rules about notice, storage fees, and sale of the unit vary, so check your state law and get signed work authorizations.
Most mobile techs charge either a flat trip fee or a per-mile rate, often with a minimum of one hour of labor. List the charge as a separate line so the customer sees what it covers.
Invoice the administrator for authorized labor and parts, include the claim number and failure description, and bill the customer only for the deductible or any non-covered items. Keep photos and the authorization on file.
Send a RV Repair estimate for approval, then turn it into an invoice when the work is done.
