Freightliner M2 Super C RV Windshield Replacement

Super C motorhomes built on the Freightliner M2 106 Business Class chassis keep the factory truck cab, so the windshield is a standard commercial two-piece M2 set costing $700–$1,800 installed. Unlike Class A coach glass it is stocked by heavy-truck glass suppliers nationwide, which makes it one of the fastest large-RV windshields to replace.

Truck cab glass, not coach glass

On a Super C, the coach body is built behind an unmodified Freightliner truck cab. The windshield stays a commercial M2 part, so heavy-truck glass distributors stock it and any truck glass shop can install it — a rare advantage among 40-foot RVs.

Everything behind the cab — the coach entry door glass, side windows, and any bonded panorama window — is the RV builder's part and follows normal RV lead times.

M2 Super C windshield cost

Truck glass is $250–$800 per pair with install at $350–$700 and mobile trip fees $0–$200. Heated and acoustic variants exist on later builds and add $150–$400 per side.

Single panel: $400 – $1,000 installed
Two-panel set: $700 – $1,800 installed
Heated or acoustic variant: add $150 – $400 per side
Coach body window: $350 – $1,200

Height and access considerations

An M2 cab sits high, so mobile installers need a work platform or scaffolding to bond the upper edge properly. Ask whether the mobile crew brings a platform; installs done off a ladder are where poor upper-bead adhesion and later leaks come from.

Freightliner M2 106 / Business Class Glass FAQs

How much is a Freightliner M2 Super C windshield?

$700–$1,800 installed for the two-piece set, or $400–$1,000 for a single side — far less than an equivalent-length Class A coach panel.

Can a truck glass shop do my Super C?

Yes for the cab windshield, since it is a standard M2 commercial part. Coach body windows behind the cab still need an RV glass specialist.

Why is Super C glass cheaper than Class A glass?

The panels are mass-produced commercial truck parts rather than low-volume curved coach panels built to a single RV maker's cap.

How long does the job take?

Three to five hours for a two-piece set with a 4–8 hour cure before driving. Sourcing is typically under a week.
