Decisions about seating and purpose are the first step in choosing the best Sprinter van model. You can fine-tune your choice by opting for 2500, 3500, or 4500 models. Each offers different capabilities. All Passenger models are Sprinter 2500s. A 3,307-lb payload capacity is available on the 144″ wheelbase versions. Sprinter 2500 Cargo vans can hold up to 4,211 lbs in the 144″ wheelbase configuration. Sprinter 3500 Cargo vans are for drivers who need to take heavier equipment or move larger loads. 3500 Cargo models can hold up to 4,699 lbs (144″ standard models). Extended (XD) vans increase this to 5,622 lbs. Sprinter 4500s are for drivers who consistently carry heavy loads or have weighty equipment necessary for a mobile workshop. Standard 4500 models (144″ wheelbase) can tote an impressive 6,735 lbs. Cargo volume can be important if you carry material, make deliveries, or need the maximum space for customization. Standard vans can hold 319 cu ft of cargo. High-roof and extended (XD) models can increase volume. For example, the 3500XD High Cargo van accommodates 430 cu ft. High models can also allow extra space with a standing height of 79″, making them ideal for recreational customizations or mobile workshops.
