Part Removal / Relocation – Trailer
Parts such as lights, spare tire racks, and license plates in the air stream can increase drag. Removing or relocating these parts can help reduce drag and improve fuel economy.
Although each part may have a minor effect on drag and fuel economy, when combined these parts can add up to reduced fuel efficiency by as much as a few percent. Each 1% in fuel efficiency can be up to $700 in annual fuel savings, decreasing the value of these add-on parts and making them good candidates for removal.
