Tiffin Allegro windshield & glass replacement
A Tiffin Allegro windshield is a two-piece curved laminated coach set costing about $1,500–$3,600 installed depending on whether it is an Allegro gas model, an Allegro RED, or an Allegro Bus. Tiffin's parts department supplies panels directly by VIN, which is the fastest route.

'Allegro' spans a wide range at Tiffin — from the F-53 gas Allegro up through the Allegro RED and the PowerGlide-chassis Allegro Bus — and the windshield gets larger and more expensive as you climb.
Tiffin's owner-facing parts support is unusually good for this industry. Calling with your VIN generally produces the correct part number faster than working through a third-party distributor.
What to know before you order Tiffin Allegro glass
- Identify the exact Allegro line before quoting. An Allegro Bus panel can cost roughly double an entry-level Allegro gas panel of the same model year.
- Tiffin caps changed with each front-end restyle; model year is decisive and the VIN is the only reliable input.
- Allegro coaches commonly show stress cracks originating at the lower outboard corner after leveling on uneven ground — worth checking jack pads and leveling habits after a replacement.
- Ask about the divider bar and reveal molding when ordering; replacing them during the set costs little and prevents a return visit for a leak.
How to get an accurate Tiffin Allegro quote
- Have the VIN ready — on a class a (gas and diesel) the glass follows the Ford F-53 / Freightliner XC / PowerGlide, and model year decides the part.
- Say whether the damage is a chip, a running crack, a stress crack with no impact point, or dual-pane fogging — each is a different job.
- Ask whether the quote is OEM or aftermarket glass, and whether freight is included.
- Confirm the safe drive-away time so you know when the coach can move.
- Get the workmanship warranty on leaks and stress cracks in writing before work starts.

Tiffin Allegro Glass Questions
How much is a Tiffin Allegro windshield replacement?
Roughly $1,500–$3,600 installed for the two-piece set. Allegro Bus panels sit at the top of that range; Allegro gas models at the bottom.
Should I order glass from Tiffin or a glass shop?
Either works. Tiffin parts with your VIN is the most certain match; an RV glass distributor may be faster and cheaper if they stock the panel for your cap generation.
Can one half be replaced on an Allegro?
Yes. The halves are independent panels and single-side replacement is routine.
