RV and Truck Panel Replacement in Yorba Linda

Three conditions. When the panel is torn or holed beyond what the material will accept. When the damage crosses enough compound curvature that rebuilding the contour accurately would take longer than fitting a new part. And when repair hours simply exceed the cost of the panel plus installation, which is common on trucks and vans where stamped panels are inexpensive.

There is a fourth condition specific to RVs: water. A sidewall that has taken water into the substrate is not a candidate for surface repair regardless of how the outside looks. Wet lauan and saturated foam core have no structural value, and skinning over them buys a season. That section comes out.

What pushes the decision back toward repair on RVs is parts. When the panel does not exist, repair or fabrication are the only options, and we will tell you honestly which of those two we are recommending and what it costs.

At a location the eye already expects a line. A graphic edge, an existing molding, a compartment door surround, a window frame edge, a slide perimeter or a cap joint. A seam placed at one of those disappears because there was already visual interruption there.

A seam placed in the middle of a flat panel is visible forever regardless of how well it is bonded and finished, because you are looking at a butt joint in a laminate that will move seasonally. It will telegraph. Not immediately, but reliably.

Seam construction matters as much as location. A properly done sidewall section joint uses a backing splice bonded behind the joint so load transfers across it, not a butt joint held together by filler. The splice is what keeps the seam from working loose over years of road input, and it is one of the differences you cannot see at delivery.

• Seam at a graphic edge, molding line or existing trim break
• Seam at a window, compartment or slide opening perimeter
• Backing splice bonded behind the joint to transfer load
• Never a butt joint in open sidewall held by filler alone
• Full length replacement where no legitimate seam location exists

We fabricate it. Fiberglass panels and sections can be moulded from a pattern taken off the opposite side of the same vehicle, which produces a part with correct curvature and texture. Aluminum is formed in house. Structural backing and framing members are fabricated to match original section and gauge.

This is not a small capability and it is the reason older coaches are repairable here at all. A large share of RV manufacturers that built the coaches now needing panels have been out of business for twenty years. A shop that can only install supplied parts has nothing to offer those owners.

The tradeoff is time. Making a mould, pulling a part, trimming and fitting it takes days that ordering a part does not. We say that clearly at estimate rather than letting the schedule drift, because a fabricated panel job is measured in weeks.
