When renting equipment, be aware of potential hidden fees such as delivery and pick-up charges, which may be flat or mileage-based. Fuel surcharges, damage waivers, and cleaning fees for equipment returned in poor condition can also add to the total cost. Late-return penalties and overtime charges should be considered when planning your rental period.
