Expect **$25,000 to $150,000+** and **ten to thirty weeks**. ## What is a full unit collision restoration? A full unit collision restoration strips the vehicle to its frame, verifies and corrects the structure, then rebuilds shell, systems and interior outward. We run these projects at our 35,000 square foot Yorba Linda shop for Rancho Santa Margarita owners whose coach is worth more than the damage. - The repair or total loss decision has to be settled before work starts - Interior comes out completely, which is what makes the hours large - Progress is billed and photographed in stages, not at the end - Agreed value policies change this conversation more than any other factor ### Key facts | Item | Value | | --- | --- | | Price range | $25,000 to $150,000+ (120 to 800 labor hours at $210 per hour) | | Labor rate | $210 per hour (Body and paint department, with mechanical sublets billed separately) | | Typical duration | 10 to 30 weeks (Driven by parts, interior scope and carrier approval cycles) | | Deposits | 50 percent over $2,000 (Plus 25 percent at parts arrival on jobs over $10,000) | | Shop capacity | 35,000 sq ft (Long term project bays for units up to 45 feet) | Some units arrive on a lowboy with the roof rail collapsed on one side, or with three quarters of the shell opened up and the interior soaked. There is no panel to replace and no member to pull. The coach has to be taken back to the part of it that is still true, which is usually the frame, and then built outward again. This is the smallest category we run by volume and the largest by hours. It is also the only one where the first serious conversation is not about repair at all. It is about whether rebuilding this particular unit makes sense against what it is worth and what the policy says it is worth, because those two numbers are frequently not the same. ## What a full unit restoration actually means It means the vehicle is disassembled until we reach material that measures correct, and everything outward of that boundary is rebuilt. On a rollover the boundary is usually the chassis and the floor structure. On a severe side impact it might be the opposite wall and the roof. The distinguishing feature is not the size of the number, it is that the unit is taken apart as an assembly rather than repaired as a set of damaged parts. That approach exists because at a certain damage level, sectional repair stops being reliable. Three walls that each moved slightly do not add up to a coach that is square, and a slide room installed into a shell built from approximations will never seal. Once enough planes are compromised, correcting them together is both faster and the only way the finished unit behaves properly. - Rollovers and units that came to rest on a corner - High energy impacts that opened the shell rather than dented it - Fire and heat damage extending past the visible scorch boundary - Vintage, converted and custom units where replacement does not exist ## The valuation conversation comes before the repair conversation Every one of these projects begins with a question that has nothing to do with welding: does rebuilding this unit make financial sense. We answer it with a documented scope, a parts position and an honest hour count, then set that against what the coach is worth and what the policy actually pays. Some owners read that package and take the settlement instead, which is a good outcome bought for the price of an assessment. Policy type moves the answer more than any other factor. An agreed value policy on a well kept diesel pusher supports rebuilds that an actual cash value policy on the same coach would never justify, and owners rarely know which they hold until it matters. Then there is the category where arithmetic is beside the point: vintage coaches and custom conversions that cannot be replaced by writing a check. ## Stripping a coach back to the frame The interior comes out completely and it comes out cataloged. Every cabinet, appliance, panel and wiring run is tagged with its location and photographed before it moves to on site storage. This is unglamorous work that consumes real hours, and it is also the thing that makes reassembly a matter of reading a record rather than reconstructing a floorplan from memory four months later. Then the shell comes off. We follow the damage outward until the framing measures true and the substrate sounds solid, and on a rollover that line typically sits far further from the point of impact than the photographs suggest. The boundary is set by moisture meter readings and by measurement, never by where the paint stops looking bad to somebody standing outside. > **warning:** A unit that sat open to weather after the incident carries two damage sets. Impact damage and exposure damage are documented separately, because carriers frequently treat them differently and combining them costs the owner. ## Rebuilding the shell one plane at a time Structure gets rebuilt from the frame outward, and each plane is proven before the next one goes on top of it. Floor structure is squared and checked on the diagonal. Walls are set plumb and verified at multiple stations along the length rather than at the ends. Only then does the roof structure go on, because a roof built onto walls that lean will telegraph that lean into the roof line permanently. Framing is fabricated here. Aluminum stock, steel tube and structural plate are cut and welded in house, which is what makes these projects possible on units where the original member was never sold as a part. Substrate goes back as Azdel or lauan depending on what the unit was built with, and skin is bonded rather than fastened wherever the original construction was bonded. ## Systems, wet testing and interior reinstallation Before any finished surface goes back, the shell gets tested. The roof is flood tested, window and door openings are checked, LP lines are pressure tested and the fresh and waste water systems are proven. Finding a leak after cabinetry is installed is one of the most expensive mistakes available on this kind of project, and the test sequence exists specifically to prevent it. Then the cataloged interior goes back in reverse order. Components that were soaked do not return at all. Particle board cabinetry that got wet has changed its material properties permanently and will delaminate through the first humid stretch, so it is replaced rather than dried and refitted. Appliances that saw fire or extinguisher residue are replaced as a matter of course. ## Schedule, staged billing and what the file is worth later Ten to thirty weeks is the honest span. The floor belongs to units with intact interiors and available parts. The ceiling belongs to rollovers with full interior replacement, custom fabrication and a carrier approval cycle that adds a week every time a supplement is filed. Because these run long we bill and photograph in stages, so an owner who cannot visit weekly still sees where the money and the vehicle actually are. A project this size takes a 50 percent deposit at authorization and a further 25 percent when parts arrive, standard on jobs over $10,000, and nearly every component is special order. The documentation matters beyond the repair too: a rebuilt coach delivered with a complete photographic and measurement record is a very different asset at resale from one delivered with a stack of invoices. > **price:** Hazmat handling at $45 applies where LP, refrigerant or fire residue is present. On restoration work that is the normal case rather than the exception. ## Projects we take on and projects we turn down We have the bay space for units to 45 feet and we hold long term projects indoors rather than pushing them outside between phases, which is the practical constraint most shops hit first. What we decline are units where the chassis itself is beyond correction, and units where an owner wants a rebuild started before the valuation question has an answer. Both of those end badly and we would rather say so at the counter than three months in. The chassis case is simple: if the rails cannot be brought back to specification, everything built on them inherits the error. The valuation case is worse, because an owner who starts and then loses the total loss argument has funded a project nobody planned to buy. ## Cost $25,000 to $150,000+, based on 120 to 800 labor hours at $210 per hour. Written repair estimate is $150, credited in full against an authorized repair. All work is performed in shop. ## Questions and answers ### How do I know if rebuilding my coach is worth it? You compare a documented scope against the policy valuation basis, not against a guess. We produce the scope, the parts position and the hour count first. Agreed value policies frequently support a rebuild that an actual cash value policy on the identical unit would not, and most owners do not know which they hold. ### Does the entire interior have to come out? On a strip to frame rebuild, yes. Walls cannot be rebuilt around installed cabinetry and no leak test is meaningful with finish in place. Everything is tagged by location and photographed before it moves to storage, so reassembly follows a record rather than someone remembering how it looked. ### My unit sat open in the rain after the accident. Does that change things? It adds a second damage set. Rot from exposure is documented separately from impact damage because carriers often treat the two differently, and merging them tends to cost the owner. Moisture meter readings taken once the shell is open establish the boundary of each. ### How is a months long rebuild billed? In stages, with photographs at each one. A 50 percent deposit is taken at authorization and a further 25 percent when parts arrive on jobs over $10,000. Special order components are not refundable once placed, and we identify those line items before ordering anything. ### Will a rebuilt coach be harder to sell later? Not with a complete file behind it. Buyers and inspectors ask what was done and how it was verified. A rebuild delivered with staged photographs and measurement records answers that concretely. A rebuild delivered with only invoices leaves the buyer guessing, and guessing costs you at the negotiation. ### Do you rebuild vintage and custom converted units? Yes, and they are frequently the strongest candidates, because replacement is not available at any price. We fabricate framing in house for units where the original member was never sold as a part. The limit is the chassis: if it cannot be brought back to specification, we say so rather than build on it. --- Source: [OCRV Center](https://ocrv.me/services/collision-repair/full-vehicle-collision-restoration/).
