The Fontaine Advantage

Quality Engineered into All We Do

Quality at Fontaine Modification is not simply a slogan or a poster on the wall. We’ve designed our entire work process, from user requirements definition to design engineering to pre-delivery testing, to be focused on quality outcomes and consistent repeatability. Every finished truck, from first to last, is quality engineered throughout.


For new designs and fleet orders we often invite the customer for a "Pilot Review" of the first vehicle. This extra step assures customer satisfaction with our designs.

Engineering Expertise, Rapid Prototyping, Problem Solving 

Experience Counts

With 40+ years of engineering and modification experience, Fontaine Modification is able to build upon our deep understanding of existing OEM platforms to professionally solve even the most complex custom modifications. Working from a “think and plan first” perspective, we use our engineering capabilities to design the best and safest solution for every application.


Our long history and industry insight enable us to provide you with the guidance and proven design expertise to help you select the most effective modification possible and comply with FMVSS regulations

OEM Integration Saves Shipping Cost and Time

Relationships Matter

Fontaine has established partnerships with the leading truck OEMs. Our modification centers are strategically located near their manufacturing facilities for ultimate customer convenience and ship-thru arrangements. As a result, we can move your new trucks directly from the OEM assembly line to one of our modification centers and then return them to the OEM equalized freight system and on to their final destination with limited shipping costs. Your new trucks will get out into the field in the shortest amount of time possible.

Small Company Care with Big Company Security

Despite our leadership role in the industry, Fontaine is still very much the small business it was 40 years ago; we’ve just added some big company benefits. A call to any of our modification centers will get you into the GM or engineering production manager. 

In addition to this personalized attention, you’ll also receive the industry’s strongest warranty coverage, providing full and comprehensive indemnification (not just an insurance policy), backed by the financial strength and reputation of Marmon Holdings and our parent company, Berkshire Hathaway.
