A 2016 Tiffin Allegro Bus 37AP on a Powerglide chassis needed both windshield halves replaced after a rock strike cracked the driver side and the passenger side showed edge delamination. Both panels were set in a single full-day appointment in Phoenix with new gaskets, and the final invoice came to $4,180 for the pair including glass, gaskets and labor.

"They caught the delamination on the second panel that I hadn't seen. Doing both at once saved me a second appointment and a second mobilization fee."Verified customer — Phoenix, AZ
Why both halves were replaced together
On a two-piece Class A windshield the panels share a center divider and a common gasket line. Replacing one side against an aged panel usually means pulling the divider twice, paying two mobilization fees, and living with a visible tint mismatch between old and new glass.
In this case the passenger panel already showed edge delamination — the milky cloudiness where the laminate interlayer separates from the glass. That is a failure in progress, not cosmetic, so replacing it in the same visit was both cheaper and safer.
How the insurance claim went
Comprehensive RV policies cover glass subject to the deductible, and on a $4,180 job a $500 deductible makes filing obviously worthwhile. The carrier approved on inspection photos alone and the shop billed directly, so the owner paid only the deductible at completion.
The one thing that speeds a coach-glass claim is documentation: build sheet, VIN, dated photos of each panel, and a written quote that itemises glass, gaskets and labor separately.
Frequently Asked Questions
How much does a Class A two-piece windshield cost?
This job invoiced $4,180 for both panels including new gaskets and a three-technician crew. Single-panel Class A replacements typically run $1,500–$3,000 depending on the coach and glass availability.
Can Class A coach glass be replaced on site?
Yes. This one was done in the owner's driveway. The requirements are level ground, roughly 12 feet of clear working space across the front cap, and enough room for a three-person crew to handle panels that weigh 90–140 lb each.
How long did the glass take to arrive?
Nine days. Coach-specific curved glass is not a stock item — the exact mold is tied to the model and build year, so ordering early is what controls the schedule.
