Testimonials
R&R Trucking Inc.
During pre-production testing Kevin McKelvy, Vice President of Administration at R&R Trucking Group wrote: "We wanted to test a high mileage engine. I selected a tractor that is slated for sale. This tractor has a long history with us and is equipped with a 686,000 mile Detroit engine. Well Done! I look forward to your ability to mass produce these units and move into the market place." Kevin provided these fuel economy measurements from the truck's onboard systems showing the improvement gained by installing Radiant Halo Seven™.
