Nathan Roberts, owner and President of G. D. Roberts & Co., Inc. and Company and Robbie Smit, Area Manager North America Westport Fuel Systems – Prins.

We enjoy seeing work trucks for the propane industry being operated on Autogas. EPA certified systems are readily available for these work trucks and what is better than driving on the same fuel that you also sell and deliver? Fisk is making that possible using the Prins VSI Autogas fuel system technology offered by Alliance AutoGas. On a custom vehicle build customers can check the box on a propane Autogas conversion and the vehicle build and Autogas upfit will be executed under the same roof.
Fisk has been offering the Autogas upfits since 2007. From their long experience with the propane industry and Autogas they have found that working with Alliance AutoGas and Prins is a great fit for them and a product they can confidently use in their truck builds for their customers.
Robbie Smit, Area Manager North America for Prins: "I have known Fisk for quite some time from our collaboration, their presence in the industry and how they have been promoting Autogas. We pride ourselves being an innovative company and I see this in Fisk as well. With their assets, especially with parent company GD Roberts manufacturing in the same buildings and their own vision, I see that they can prototype and manufacture in house very efficiently to see if something works and implement it. I had the pleasure of visiting Fisk in 2025 and take a tour of their facilities, and I was very impressed by what this company does everyday. We’re happy that a company like Fisk is part of our global network and promoting and using Autogas."
About Fisk & GD Roberts
Fisk has been making boom trucks since 2004, and started installing autogas systems on trucks within three years of that, around 2007. Nathan Roberts: “We've stayed with Alliance AutoGas over the years because of their amazing service and systems. They serviced customers quickly and reliably on the few issues that have come up, and their systems are easy to install. Alliance has been excellent with our staff when we have had a difficult install and have provided a tank size that allows us to have boxes on both sides of our trucks. We appreciate the relationship we've built with Alliance and Prins over the years, and are so proud to be able to offer a reliable and efficient Autogas conversion option for our customers”.
