We work off purchase orders generally although for an order of this size we'll expect 20% down. The trucking company is huge, over 5,000 prime movers and cab-chassis vehicles so they're good for it.
Just on the diesel cost...It's $2.20/L here. (3.78541 litres in a gallon.) That's a $264 cost to fill my Land Cruiser.
I'd say parking up the prime mover and having a little break is a good idea. You deserve it anyway.
