Why don't you look at the other uses in addition to hauling the #400 of milk (2 adults) 3 times a week.  6 hours of time should not be the over riding deciding factor in a vehicle purchase.  The Prius has a VERY LOW ground clearance, I witnessed one being serviced at a garage and they literally had to lift the body up manually to get to clear the lift arms.  It was an older type lift but made me take notice.  I like the diesel suggestions as you have more low end torque for loads.
