Jerry, the Iveco was single rear wheels and a bit bigger than a Merc Sprinter. Owner says he can get close to 40mpg when no load. My boy has a Mer Sprinter just converted to a motor home last year from being a disabled bus with a lot of windows. The Merc was just 2500 pounds bought last year. That one is fairly old but very light use transporting OAPs to the shops or Hospitals.
Peugeot engines are very long lasting and usually manage over 160,000 miles. My 2 boys who mend these vans would agree that the transit is to be avoided if high mileage and older due to the underside rotting out.
Merc seems to be the outstanding van, but the Iveco in the garage has proven to be durable. Possibly due to a lot of long distance running
