411,046 Miles on our 2015 Freightliner Cascadia
Lifetime Fuel Mileage 12.23

The “Caff-cadia” had some crazy modifications performed before we brought her home. She started out getting good fuel mileage and that has not changed. Between our fuel mileage and the fuel sur charge (FSC) we are very pleased with our Freightliner.

At the first of the year, Bob took off the full skirting as we are preparing the truck for a driver when we purchase our new truck. We felt that the skirts would place to much pressure on a driver as they were very low and each dock and dip in the road had to be looked at carefully as to not drag the skirts. Every once in a while, our skirts had to be lifted to cross over a particularly difficult bump in a driveway. Was the extra work worth it? Yes, as the owner of the truck.

We are in the process of spec’ing our next Cascadia and are hoping for even better fuel mileage. The new Cascadia will be a little different than our current truck with the main difference we are going with a twin screw and a heavier front end. More on spec’s when we get the truck ordered.
