I think the sprinter will outlive it's usefullness. A dedicated work truck tends to get beat up and bumped into when used in the city and may not look very well in ten years after all the abuse.
I am also not sure about it holding up to the constant weight of a work truck. Take a look under the van and it has no frame, unibody, the axle looks very small as well as the front suspension. As a delivery truck I doubt they see the weight a electrician would put in one daily
