Pros & Cons
Pros
- Widest cargo van available — 1920mm allows a full east-west bed for most people
- Front-wheel drive means flat, low cargo floor with no driveshaft hump
- Lowest starting price of any full-size conversion van in the US
- Highest payload capacity (1800 kg) provides the most weight budget for builds
- Based on the Fiat Ducato platform — proven worldwide reliability
Cons
- Only gasoline engine available in the US — no diesel option for fuel economy
- FWD means limited off-road capability compared to RWD/AWD competitors
- Lower ground clearance makes rough roads and boondocking more challenging
- Pentastar V6 fuel economy is poor (13-17 mpg) for long road trips
- Boxy styling and tall height make crosswind driving more noticeable
