Workhorse Chassis RV Windshield Replacement

Workhorse W20, W22, and P32 chassis coaches were built roughly 1999–2010 and the chassis maker is long gone, but that does not orphan your glass: the windshield belongs to the coach builder — Fleetwood, Monaco, National RV, Damon, Georgie Boy — and most panels are still available or cross-referenceable at $1,000–$2,600 installed for a two-piece set.

Sourcing glass for a discontinued chassis

Owners of Workhorse-based coaches are often told the glass is unavailable. In practice, the chassis brand is irrelevant to sourcing — what matters is the coach maker and model year. Fleetwood Bounder, National RV Dolphin, and Damon Challenger panels are still catalogued by RV glass distributors, and where a part number is dead, a specialist can cross-reference a shared panel from a sister model.

Flat panels are the safety net: if nothing is catalogued, a specialist can cut and edge-polish a matching laminate blank to the template of your old glass.

Search by coach brand and model, never by 'Workhorse'
Sister brands under Fleetwood and National often shared panels
Flat glass can be fabricated from stock laminate as a last resort
Salvage yards specialising in RV caps are a legitimate source

Workhorse-based coach glass cost

Expect $450–$1,500 per pair for glass, $450–$850 for install, and a real chance of $200–$800 in cap and pinchweld prep given the age of these coaches.

Single panel: $600 – $1,500 installed
Two-panel set: $1,000 – $2,600 installed
Custom-cut flat replacement: add $200 – $600
Rot / delaminated cap repair: $200 – $800

Age-related issues to expect

These coaches are 15–25 years old. Original urethane has hardened, reveal moldings are brittle and often crack on removal, and fiberglass caps can be delaminated around the opening. Budget for new moldings and cap repair rather than being surprised by them mid-job.

Workhorse W20 / W22 / P32 Glass FAQs

Can you still get a windshield for a Workhorse W22 motorhome?

Yes. The panel is a coach-builder part, so search by your coach brand and model — Bounder, Dolphin, Challenger and similar panels are still available or cross-referenceable.

How much does it cost?

$1,000–$2,600 installed for a two-piece set, plus $200–$800 if the fiberglass cap or pinchweld needs repair, which is common at this age.

What if the part number is discontinued?

A specialist can cross-reference a sister model's panel or fabricate a flat replacement from stock laminate using your old glass as a template.

Is it worth replacing glass on an older coach?

Usually yes. A cracked structural windshield fails inspection in many states, leaks into the dash, and cuts resale value by more than the repair costs.
