Dennis,
I join the group that wonders why you want to know this, please break the suspense.
If you are trying to decide on the size alternator you need then just do as the others have suggested and add up the total of the fuses or slightly less.
For airplanes we use the total fuse size just to be safe.
Some of the things you listed do not draw current all the time or do not draw the same current for very long and most things required to operate the vehicle are in this category.
Of course this does not include monster sound systems and light systems.
