Disc brakes are not subject to "fade" which occurs when drum brakes overheat and lose the ability to stop, another advantage of disc brakes is that they tend to stop in a straight line unlike drum brakes which often "pull" to one side. Yet another advantage of disc brakes is that they self adjust by drawing brake fluid in behind the piston while it is common for the self adjusters in drum brakes to seize due to corrosion then the drum brakes quit adjusting then the brake pedal goes lower and lower.
To maintain directional control during a hard or panic stop. Think about it. If your brakes lock, you go into a skid and lose control of the car. Anti-lock brakes prevent the brakes from locking up, and throwing the vehicle into an uncontrollable skid. This system allows maximum deceleration without having the brakes lock, which, in turn, allows the driver the ability to maintain control of the vehicle while coming to the most rapid stop possible.
As your hauling truck is being put under much strain, it does lose value quicker than one which has done less work.
Probably. It isn't your truck...it's hers...and she can't afford it.
