RVs and Motorhomes
Vintage and Classic RVs Repair
The short answer
Vintage coaches, from riveted aluminum Airstreams and Avions to GMC motorhomes and 1970s Class A units, use construction and parts that no longer exist. Repair means fabrication, riveting, wood framing replacement, and sourcing rather than ordering. We do that work in shop in Yorba Linda.
01
What we see on vintage and classic rvs
Vintage RV work is a different trade from modern RV repair, and the reason is that almost nothing on the vehicle is a replaceable part. A riveted aluminum monocoque like an Airstream or an Avion carries its load in the skin itself through the rivet lines, which means a dent is a structural event and a corroded panel cannot simply be patched over. Repair means drilling out rivets, forming replacement panel to the correct radius, and bucking new rivets to the original pattern. On a GMC motorhome you are dealing with a molded fiberglass and aluminum body over a front wheel drive chassis whose body panels have not been produced in decades. On a 1970s Class A you are usually dealing with wood framing behind an aluminum skin, and the wood is the part that failed.
That wood is the recurring theme. Coaches built before laminated construction became standard used dimensional lumber or plywood framing behind screwed aluminum, and every screw through that skin is a potential water path into wood that has no rot resistance at all. Fifty years of Southern California weather cycles, dry heat opening the sealant and concentrated winter rain finding it, produces framing that has been wetting and drying so long the wood has lost its fastener holding ability even where it looks intact. We routinely find that the visible soft spot is a small part of what has to come out.
Value on these vehicles is tied to originality, which changes how we approach the work. There is a real tension between a correct restoration and a durable repair, and it should be settled before anyone picks up a tool. Modern sealants and adhesives outperform the originals substantially, and modern insulation is better in every way, but a buyer paying a premium for an original interior does not want it modernized. We ask which you are optimizing for at intake and write the scope accordingly.
Location: All work is performed at our Yorba Linda facility. We do not offer mobile, roadside, or fleet route service.

What makes this vehicle different
- Riveted aluminum monocoque or aluminum skin over dimensional wood framing
- Structural load carried by skin and rivet lines rather than by a separate cage
- Obsolete body panels, trim, glass, and appliances with no factory supply
- Single-pane glass and original window frames with no modern gasket equivalent
- Original wiring and plumbing that predates current standards and materials
- Value driven substantially by originality of interior and exterior finish
- Chassis and running gear that in many cases has no modern parts crossover

What actually fails, and why
Wood framing rot behind aluminum skin
Every screw through the skin is a water path into untreated lumber. Decades of dry heat opening the sealant followed by concentrated winter rain leaves framing that no longer holds fasteners even where it looks sound to the eye.
Rivet line failure and skin working on monocoque bodies
On riveted aluminum shells, load travels through the rivets. Once a run of rivets loosens, the panel starts working against the frame at every road input and the holes elongate, which shows as a line of dark smudges along a seam.
Galvanic corrosion at dissimilar metal joints
Steel fasteners and steel framing in contact with aluminum skin corrode aggressively, and coastal storage from Long Beach to Oceanside accelerates it. The panel lifts around each fastener head and the joint stops sealing without any impact involved.
Original window and frame leakage
Single-pane windows in period aluminum frames rely on gaskets and glazing compounds that have long since hardened. There is often no replacement gasket available, so the fix is fabricating a seal solution rather than ordering a part.
Unavailable panel and trim damage
A creased body panel or a broken trim section on a discontinued coach cannot be replaced from stock. It has to be formed, welded, or molded from a pattern taken off the vehicle, which is why vintage body jobs carry more hours than their size suggests.

Questions about vintage and classic rvs
Frequently asked questions
Can you get parts for a coach this old?
Sometimes we source them and often we make them. Panels get formed from pattern, trim gets fabricated, and structural members get cut and welded to match the original section. That is why vintage estimates carry more hours than a comparable modern job. We tell you at intake which items we expect to fabricate so there are no surprises mid-repair.
Should I restore it original or repair it with modern materials?
That is your call and it should be decided before work starts. Modern sealants, adhesives, and insulation outperform the originals substantially and will last far longer here. Original materials preserve value for a buyer paying for authenticity. We are happy to do either, and we frequently do a hybrid, modern behind the walls and period-correct on every visible surface.
What does it cost to replace rotted framing on a vintage coach?
A localized section of wall framing with skin removal and reinstallation typically starts in the low thousands. A full sidewall or a floor and lower framing rebuild runs well into five figures. Body and structural labor is $210 per hour. Because the extent is never visible until the skin comes off, we scope after opening rather than before.
Is a vintage coach worth repairing?
Frequently yes, and the deciding factor is the structure rather than the cosmetics. A coach with sound framing and a straight body is worth substantial work because the finishes can be redone. A coach with widespread framing rot and a racked shell may cost more to correct than it will ever be worth. We give you that assessment honestly after inspection.
Do you do pre-purchase inspections on vintage RVs?
Yes, and on these vehicles it is worth far more than on a modern unit. We check for framing rot, rivet line movement, corrosion at dissimilar metal joints, floor integrity, and evidence of previous repairs done badly. That inspection routinely saves buyers from a coach whose real cost was hidden behind fresh paneling.
