What is different about Class A, Class B and Class C RV windshields?
Reviewed by the Skyview Auto Glass technical team — NWRD-, ASE- and DINITROL-trained technicians · Updated November 2026
Quick answer
Class A motorhomes have large, often two-piece windshields that need more hands and the right equipment. Class B campervans use a van windshield matched to the base vehicle. Class C motorhomes use a cab-over windshield, also matched to the chassis. Each class is sourced from the year, make, model and VIN, and the hardest to replace is the large Class A pane.
How the three classes differ
The windshield on a motorhome follows the chassis it is built on. A Class A is a purpose-built coach on a heavy chassis, and its windshield is large and frequently split into two pieces that meet at a center divider. A Class B is a converted van, so its glass is the van’s own windshield. A Class C is built on a cutaway chassis with a cab-over bed, and its windshield is the cab’s glass.
Because the glass follows the chassis and coach, the exact pane is confirmed from the year, make, model and VIN before ordering. The install difficulty rises with the size of the pane, which is why the Class A two-piece windshield is the hardest of the three to replace.
A Class B or C windshield is closer to a truck or van install — a single pane handled by one or two technicians. A Class A two-piece windshield is a different lift entirely, with each half set and sealed against the center divider in turn.
RV windshields by class
| Class | Windshield type | What makes it different |
|---|---|---|
| Class A | Large, often two-piece | Big, heavy panes need more hands and the right equipment |
| Class B | Van windshield | Matched to the base van the campervan is built on |
| Class C | Cab-over cab windshield | Matched to the cutaway chassis cab |
Each class is sourced from the year, make, model and VIN — chassis and coach — before ordering.
The hardest to replace
A Class A two-piece windshield is the most demanding of the three: the panes are large and heavy, the opening is wide, and setting the glass safely calls for more than one technician and equipment sized to the job. Class B and C glass follows the chassis cab and is closer to a truck or van install.
More questions about RV windshield classes
Are Class C windshields the same as a van?
A Class C is built on a cutaway chassis, so its windshield is the cab’s glass rather than a van pane. It is matched to that chassis, not to a converted van like a Class B.
Do Class A motorhomes have two-piece windshields?
Many do. The opening is wide enough that a single pane would be too large and heavy to handle, so the glass is split into left and right halves that meet at a center divider.
Which RV windshields are hardest to replace?
The large Class A two-piece windshield. The panes are big and heavy, the opening is wide, and setting the glass safely needs more hands and the right equipment than a Class B or C.
