Heh, I know somewhat about the conversions. Here in Canada the Imperial gallon, US gallon, and litres are all still in use. New car gas mileage shown on the window stickers are expressed in Imp. Gallons and Litres/100km. Most Canadians can flip between metric and the US system pretty quickly thanks to our giant neighbor to the south with whom we do loads of business. I had to use both systems in college. In fact, pretty much the only metric drawings I see at work are either foreign or Canadian Government, everything else is US system.
That is a sweet truck and a great load capacity for such a small vehicle! It's basically a small lightweight half ton truck. I looked them up locally, a nice one will run me 5000.00 (!) here in the "rust belt" (ie the whole country less AB+BC).
