I'm not at liberty to say how much they are paying me for use of the truck, but it is substantial.
I'm paid for each day the truck is used in filming--that is not every day and it depends on the filming schedule.
As of now, there is one more day this week and then the schedule does not call for any further use of the truck. But.... There is a short sequence with some farm workers and that remains on the table. If the director calls for the scene (currently not on the schedule) then that would be one more day, and if I am not working, I would be able to attend the filming and do the driving.
It is horribly boring to watch a production. The peole who are on the production team are very busy, however.
In the final analysis, the total payment will be 4 figures, and the first number is not one.
