    Motorhome Windshield Replacement

    Typical cost: $400 – $5,000 per set

    Motorhome windshield replacement runs $400–$900 for a Class C chassis windshield, $900–$2,000 for flat two-piece Class A glass, and $1,500–$3,000+ per side for curved Class A panels. Expect a two-to-four-hour mobile install plus a safe drive-away time of one to twenty-four hours depending on the urethane and the temperature.

    Motorhome windshield replacement varies more than any other glass job on the road. A Class B Sprinter windshield is a catalog part any competent shop can order. A curved two-piece Class A windshield is a low-volume, coach-specific laminate that may take weeks to source and a three-person crew to set.

    Knowing which category your motorhome falls into tells you what to expect on price, lead time, and who is qualified to do the work.

    Class A motorhome windshields

    Class A coaches use two large panels split by a center post, in either flat or curved form. Curved glass, standard on most diesel pushers and later gas coaches, is molded to a radius specific to that manufacturer and body shell — there is no universal substitute.

    Because the windshield bonds into the fiberglass front cap, it carries structural load. Installation demands proper glass handling equipment, high-modulus urethane, and correct setting-block placement. This is the job that most general auto glass shops decline.

    • Curved two-piece: $1,500 – $3,000 per side installed
    • Flat two-piece: $900 – $2,000 per side installed
    • Lead time on discontinued or low-volume molds: 2 – 8 weeks

    Class C motorhome windshields

    Class C units are built on a cutaway van or truck chassis — most commonly the Ford E-350/E-450, Chevrolet Express 3500/4500, or Ram ProMaster. The windshield is the chassis windshield, which means normal automotive glass availability and pricing.

    The complication is access. The overcab bunk and its fiberglass cap sit directly above the glass, so the installer needs room to work and may have to remove trim the chassis manufacturer never intended to come off in an RV configuration.

    • Typical installed cost: $400 – $900
    • Usually available same week

    Class B camper van windshields

    Class B vans use Mercedes Sprinter, Ford Transit, or Ram ProMaster glass. These are widely stocked, but newer vans carry forward-facing cameras for lane keeping and emergency braking mounted to the windshield. That glass must be replaced with a camera-compatible panel and the system recalibrated after installation, which adds cost.

    • Standard glass installed: $350 – $800
    • With ADAS camera and recalibration: $700 – $1,200

    Sourcing glass for older and discontinued coaches

    If your motorhome is more than fifteen years old or the manufacturer no longer exists, new-old-stock and salvage are both legitimate options. Specialty RV glass suppliers keep cross-reference lists that match one manufacturer's mold to another coach built on the same shell, which can turn an unavailable part into an in-stock one.

    Have your VIN, model year, floor plan, and a photo of the full front cap ready. That combination identifies the correct mold faster than the model name alone, because manufacturers frequently changed cap tooling mid-generation.

    Frequently Asked Questions

    How much does a motorhome windshield cost to replace?

    From about $400 for a Class C on a Ford chassis to $5,000 or more for a full curved two-piece Class A set. Class B camper vans land between $350 and $1,200, with the higher end reflecting lane-assist camera recalibration.

    Why are Class A motorhome windshields so expensive?

    Each panel is laminated to a mold specific to that coach's front cap, produced in low volume with no economies of scale. The panels are large and heavy enough to require multiple installers and specialized handling, and the glass bonds in as a structural part of the cap, so the adhesive and prep work are more demanding than automotive glass.

    Can a motorhome windshield be replaced on site?

    Yes. Mobile service is the norm for motorhomes, since driving a large coach to a shop is often impractical. The main constraints are weather and temperature, because urethane adhesive needs dry, reasonably warm conditions to cure to safe strength.

    How long does a curved Class A windshield take to source?

    In-production molds are often available within a week. Discontinued or low-volume molds can take two to eight weeks. Providing your VIN and a photo of the front cap up front speeds identification considerably.
