Collision Repair for West Covina Owners

What counts as collision damage on a motorhome or trailer

Collision damage is impact damage to the body, the structure or the finish. On an RV that definition covers far more ground than it does on a car. A Class A that clips a concrete column in a parking structure can crack the front cap, bend the entry step, rack the door frame and split the lower skirt in one motion. The paint is what you see. The costly part is almost always behind it.

Most of what comes to our Yorba Linda shop from West Covina sorts into a handful of patterns. Low speed contact where a mirror, a corner or a bumper took the hit. Sideswipe damage from a lane change on the 10 or the 60, which runs long and shallow across two or three panels. Rear impact, which loads the rear cap and the frame extensions behind it. And storage lot damage, where something backed into a parked rig and nobody left a note.

Height strikes get their own category. A rig taller than the driver expects meets a low overhang, a drive through canopy or a hard tree limb, and the damage lands on the roof edge, the cap crown and the roof membrane at the same time. That is why a roof strike is rarely a simple panel job. It is a collision job and a water intrusion job stacked on top of each other.

• Corner and cap contact: cracked gelcoat, separated seams, a cap that shifted on its mounts
• Sideswipe: long shallow damage across sidewall panels, torn graphics, gouged skin
• Rear impact: bent frame extensions, cracked rear cap, damaged ladder and bumper mounts
• Height strike: crushed roof edge, torn EPDM or TPO membrane at the front seam, broken vent flanges
• Tow related damage: bent A frame, torn coupler, king pin and pin box damage on a fifth wheel

The first 48 hours after a collision in West Covina

Answer the practical question first. Get the rig somewhere secure and dry, photograph everything before anything is moved or cleaned, and open the claim. Photos taken at the scene are worth more than photos taken a week later, because they show the debris field, the position of the vehicles and the damage before anyone touched it.

If the roof, a window or a seam is open, cover it. A sheet of plastic and tape is not a repair, but it keeps two days of rain from turning a body claim into a subfloor claim. Water that gets into a wall cavity through a collision seam does not evaporate. It tracks down the wall, sits on the floor edge and surfaces as a soft spot months later, long after the claim has closed.

You choose your own repair facility in California. Your carrier can recommend a shop from its network and it can tell you what it will pay, but the choice of who does the work belongs to you. Bring the claim number and the adjuster contact when you come down from West Covina. We write the estimate at the shop and submit it to the carrier the same way we do on every claim.

How a collision estimate gets written and supplemented

A collision estimate is a line by line document. Each operation carries a labor time, each part carries a number, and refinish time is calculated separately from body time. On an RV the estimating databases built for automobiles run out quickly, so a large share of the estimate is written on manual entries backed by photos. That is normal on this class of vehicle and experienced adjusters expect it.

The first estimate is almost never the final number. It is written from what can be seen with the panels still on the vehicle. Real numbers appear during teardown, when a technician pulls the damaged skin and finds a split stud, a delaminated substrate or a wiring harness that got pinched between the sidewall and the frame. Those findings become a supplement, which is a documented addition to the original estimate with photographs attached.

Supplements are not a sign that something went wrong. On a heavy hit, two or three supplements across the life of a repair is ordinary. What matters is that each one is documented before the work is done rather than after. We photograph the discovery, write the line and wait for the carrier to approve it. Approval time is the single largest variable in how long your rig sits in the bay.

• Body labor: straightening, panel replacement and structural operations
• Refinish labor: prep, sealer, base, clear and blend time on adjacent panels
• Parts: caps, skins, glass, trim, lamps, graphics and sealants
• Materials: paint and body supply charges calculated from labor hours
• Sublet: glass, upholstery or specialty operations sent to a partner shop

Repair or replace: how the call gets made on a damaged panel

Steel and aluminum panels can be worked. Fiberglass caps and laminated sidewalls often cannot, at least not economically. The decision comes down to how the material behaves after it has been stretched. Aluminum siding that has taken a sharp crease is thinner at the crease than it was, and it will throw a shadow forever no matter how much filler goes over it. Replacement gives a flat panel and a clean seam.

On laminated sidewalls the question is whether the damage went through the skin into the core. A dent in filon over azdel that did not break the skin can sometimes be relieved and refinished. Once the skin is punctured or the core is crushed, the bond in that area is gone, and an honest repair has to open the wall, replace the core section and re laminate. Skipping that step buys you a bubble two summers later.

We make this call in front of you when we can. Panels come off, the substrate gets probed and tapped, and the decision gets photographed so the adjuster is looking at the same evidence you are. Where a repair will hold, we repair. Where it will not, we say so plainly and write the replacement instead of hiding a soft area under filler.

Hidden damage behind a clean looking dent

The most expensive collision jobs often start with the smallest looking damage. A rear corner tap that moved the cap an inch also loaded the roof to sidewall seam, and that seam is where the lap sealant lives. Sealant that has been stretched will pass water the following winter. None of that shows in a photograph of the bumper.

Here is what teardown routinely turns up on a hit that looked minor from the outside.

This is why teardown exists as its own line on the estimate. Guessing at hidden damage produces two bad outcomes: an inflated estimate the carrier will not approve, or a thin estimate that runs into supplements once the vehicle is already apart. Opening the vehicle first and documenting what is actually there is slower up front and faster overall.

• Cracked or split wall studs behind skin that still looks flat
• Slide out rooms that no longer seal because the opening racked
• Pinched or chafed 12V harness behind a struck compartment
• Bent slide rails and rollers on the impact side, common on Schwintek and Lippert In Wall systems
• Compressed insulation and wet luan along the floor edge
• Loosened cap mounting hardware that lets the cap move under load
• Cracked Hehr or Kinro window frames that pass water at the corners

Refinishing the repair so it stops being visible

A body repair is judged on the paint. Booth work here runs on a documented process: substrate prep, primer or sealer chosen for the material underneath, base coat sprayed to a sprayout card that has been checked against your actual panel in daylight, then clear. Aged RV finishes shift with sun exposure, so the code on the build sheet is a starting point rather than an answer.

Blending is what makes the repair disappear. Base coat is carried into the adjacent panel and clear is run to a natural break: a seam, a body line or the edge of a graphics band. On a long sidewall with no break, the blend has to run further, which is why refinish time on an RV panel looks high next to a car. There is simply more surface to carry.

Graphics are the other half of the job. Most factory RV designs are printed vinyl in several layers, and matching a discontinued pattern means either sourcing the original from the manufacturer or reproducing it from photographs and measurements. We plan that early, because a graphics lead time can outrun the body work and hold a finished vehicle at the very end.

Timeline: why an RV collision job runs longer than a car

Plan on weeks rather than days. A bumper and panel repair on a travel trailer might move through in a week to ten working days. A structural hit on a Class A with cap replacement and a full side refinish can hold a bay for two to three months. The labor hour band on this page describes bench time, and bench time is only part of the calendar.

Three things stretch the schedule. Carrier approval on the original estimate and on each supplement. Parts, since RV caps, skins and one piece windshields are frequently built to order rather than stocked. And cure time, since structural adhesive, laminating resin and clear coat all have to sit whether or not anyone is working.

We do not start body work before approval, because unapproved work becomes work you pay for yourself. Once approval lands the job moves. Owners driving in from West Covina usually check status by phone instead of making the trip, and we send photos at teardown, at the structural stage and again before the vehicle goes into the booth.

Getting the rig from West Covina to the shop

The shop sits at 23281 La Palma Ave in Yorba Linda, roughly 22 miles from West Covina and 30 to 45 minutes on a normal day. We are not located in West Covina and we do not offer mobile service, so the vehicle has to reach the property. Most owners take the 10 or the 60 west to the 57 south, then the 91 east to Imperial Highway. Carbon Canyon Road to the 71 is the shortcut when the 57 stacks up in the afternoon.

If the rig is not drivable, arrange a flatbed or heavy tow before you come. Tell the dispatcher the height, the length and the loaded weight, and say whether the unit can be pulled from the hitch or has to be lifted. A careless tow can bend a already compromised frame further, which is a real risk on a coach that took a rear hit. Once it arrives it stays in our yard for the duration of the repair.
