What is an upfitment?

Upfitting a vehicle means that you’re adding components and features to a vehicle so that it fits your specific needs and or wants. An Upfitment and Customization is essentially the same thing. Upfitment is usually used for Commercial Vehicles, while the term Customization is usually used when altering a personal vehicle.
