When renting a diesel generator, be aware of potential hidden fees. These may include delivery and pick-up charges, which can be flat rates or based on mileage. Fuel surcharges, damage waivers, and cleaning fees for returning the equipment in less-than-ideal condition are also common. Understanding these fees can help in budgeting accurately for your rental needs.
