Fontaine Modification recognizes that a truck direct from the factory does not meet every application need. That’s why we offer a wide range of cab modifications to customize the vehicle to fit our customers’ specific applications while meeting all applicable FMVSS standards.

Sleeper to Day Cab Conversions
Converting your integral sleeper truck into a day cab is a specialty at Fontaine Modification. OEM components are used when possible, making it easy for you to find replacement parts through your local dealer.

Low Roof Auto Hauler
Shorter is better in the auto hauling industry. Lower cab height means greater flexibility in positioning vehicles. With our engineering and design skills, Fontaine Modification will help you achieve the lowest ground to top-of-cab height available, based on the model of truck and the chassis’ basic specifications.

Raised Roof
Many emergency and recreational vehicles are built on a standard OEM day-cab/long wheel base platform. To facilitate movement from the cab into the body, Fontaine raises the cab roof, cuts a passage through the rear of the cab, creating a seamless transition to the vehicle body.

Extended Cab
With Fontaine’s extended cab modifications, we can help you get the most of your day cab. Whether you require an extra seat for passengers or a bunk for extended trips, we can provide you with the functional space you need.
