The cost of the conversion and the return on that invested capital is ultimately dependent upon the total distance you're going to drive your vehicle.
The average postal route is 50 kilometres a day. Dependent upon whether we're operating an extremely poor fuel-efficient vehicle, such a step van, which gets about 33 litres per 100 kilometres, or a more fuel-efficient light vehicle...is how far you go, and the fuel economy that it's getting, to what the return on that investment is.
I guess in a step van scenario, for example, where a van would travel 100 kilometres at double what our normal is, the return on that investment is about 2.3 years.
