## Sleeper Shells and Day Cabs Fail Differently

A day cab is a short, stiff box that takes its abuse at the corners and the steps. A sleeper is a long cantilevered structure hanging off the back of that box, tied in at a seam that flexes every time the tractor articulates over a driveway apron. Those two facts produce completely different repair lists.

On sleepers, the recurring finds are stress cracking at the cab to sleeper seam, sealant failure along the same joint that lets water into the bunk, and roof skin oil canning around the vent and antenna penetrations. On day cabs, the recurring finds are step and tank strap damage, corner post scuffing from trailer swings, and rear cab wall damage from a trailer nose that came around further than the driver expected.

Fleet collision repair and paint refinish is posted at **$1,500 to $50,000** across 10 to 250 hours. A tractor that went down on its side, needing structural correction, a reskinned sleeper side and a full livery reapplied, is what the top of that band is for. Every posted band on this site is listed on the [prices page](/prices/).

## The One Piece Hood: Hinges, Stops and the Order of Operations

A one piece fiberglass tilt hood is the single most expensive thing on the front of a tractor and the easiest to make worse in a hurry. It weighs enough that it does not forgive a misaligned hinge, and it flexes enough that a hinge out of position will crack the laminate at the mount rather than bind visibly.

- Support the hood independently before touching any hinge hardware. A hood that drops on a half removed hinge cracks at the boss, and that turns a hinge job into a laminate rebuild.
- Check the tilt stops and their cables or straps first. A stretched stop lets the hood over rotate at the end of travel and loads the hinge in a direction it was never designed for.
- Inspect the hinge bushings and the pivot pins for wear before assuming the hood is out of shape. Worn pivots produce a hood that sits low on one side, which reads as a bent hood and is not.
- Set the hinge geometry, then set the latch and the side stops, then check the fender to hood gap along its full length rather than at the two ends.
- Only after alignment is confirmed does any laminate repair get faired, primed and finished, because a laminate repaired in the wrong position is a laminate that gets cut back out.

## Fairings, Skirts, Tanks and What Holds Them On

Aero packages are the most damaged and least understood parts of a modern tractor. The panels themselves are cheap relative to the labor, and the failure is almost never the panel. It is the mounting.

Roof fairings mount to rails that bolt through the cab roof structure. When a fairing starts vibrating or sitting crooked, the rail bolts have worked loose or the rail itself has cracked at a bolt hole, and simply tightening it accelerates the crack. Chassis skirts hang off brackets that pick up frame rail holes, and those brackets take a beating from curbs, kerbstones and road debris. A skirt that has been reattached three times to a bracket that is already deformed will fail a fourth time.

Fuel tank steps and brackets are the other repeat offender. Aluminum steps and aluminum tank straps are light and corrode where they contact steel brackets, so galvanic attack at the fastener is common on trucks that have run coastal routes. Steel steps rust conventionally and usually crack at a weld. We treat those as two different repairs: aluminum gets isolated and refastened with the right hardware, steel gets cut back to sound metal and welded. Cab air suspension bags on the rear cab mounts get inspected at the same time, because a collapsed bag drops the back of the cab and puts the whole aero package out of line. Air bag suspension repair is posted at **$500 to $4,500** for 2 to 18 hours.

## Livery, Marking, Fifth Wheel Plates and the Line We Do Not Cross

Big fleet colours are usually single stage, and that is a gift and a curse. A gift because a single stage repair blends predictably and dries fast. A curse because single stage chalks under Southern California sun, so a five year old cab and a fresh panel will never match from the code alone. We spray cards, compare in daylight, and blend rather than butt the repair against a body line.

Full refinish and repaint is posted at **$5,000 to $35,000** across 40 to 250 hours. Fleet graphics and vinyl wrap runs **$1,500 to $9,500** for 10 to 45 hours, and decal removal and reapplication runs **$400 to $3,000** for 2 to 12 hours. Reflective tape and compliance marking is a separate line at **$250 to $1,200** for 1 to 6 hours, and it goes back on before the truck leaves because a repaired panel with the marking missing is a repaired panel that will get a driver stopped.

Fifth wheel plate installation is posted at **$1,500 to $5,500** for 8 to 22 hours. That is structural mounting into frame rails, done with the correct hardware and the correct hole pattern, not a bolt through job. Mud flap and fender flare installation, at **$200 to $800** for 1 to 4 hours, usually gets bundled into the same visit.

The estimator note we put on every tractor ticket reads the same way: this shop performs body, paint, structural and equipment installation. No engine work, no drive system work, no roadworthiness certification. If a tractor needs those, schedule them around our window so the truck is only down once.

## What is included

- Full walk around damage documentation with photos of both sides for colour reference
- Hood hinge, tilt stop and latch alignment check before any laminate work begins
- Fairing and skirt mounting rail and bracket inspection at every fastener hole
- Sprayout card comparison against the actual adjacent panel in daylight and booth light
- Reapplication of fleet graphics and reflective tape and compliance marking
- Wash and final photo set before the fleet contact is called for pickup

## Questions

### My roof fairing rattles at highway speed. Is the fairing cracked?

Check the mounting rail before the fairing. Loose rail bolts and cracked rail bolt holes cause most fairing movement, and retightening a bolt into a cracked rail accelerates the failure. We pull the fairing, inspect the rail at every hole, and repair the rail before refitting.

### Can a one piece fiberglass hood be repaired after a front corner hit?

Frequently yes. The hood is supported independently, the hinges and tilt stops are checked and set first, and only then is the laminate scarfed and rebuilt. Repairing the laminate before setting alignment produces a repair that has to be cut back out, so the sequence matters more than the technique.

### Do you install fifth wheel plates?

Yes, posted at $1,500 to $5,500 across 8 to 22 hours. The install is structural mounting into the frame rails with the correct hole pattern and hardware. It is scheduled as its own block rather than squeezed into a cosmetic repair visit, because the mounting has to be right.

### Why do aluminum fuel tank steps corrode so fast on some trucks?

Because aluminum in contact with a steel bracket in a salty coastal environment sets up galvanic corrosion right at the fastener. The fix is isolation and correct hardware, not just a new step. Steel steps fail differently, usually cracking at a weld, and get cut back and rewelded instead.

### Will you reapply reflective tape and compliance marking after a repair?

Yes, and it is a posted line at $250 to $1,200 for 1 to 6 hours. A repaired panel that leaves the shop without its marking restored is an incomplete repair, so it goes back on before the tractor is released to the fleet contact.

### Do you service the engine or the drive system on a tractor?

No. OCRV Center is a body, paint, structural and equipment shop. Engine and drive system service belongs to your maintenance provider, and we do not issue roadworthiness certification. We will coordinate scheduling so the tractor sits in one downtime window rather than two.
