Here's a difference in the 150 and a HD truck.
My 1-ton "SD" E-350 and yes it has a factory label that says "Super Duty" has a dana 60 semifloat 8 bolt axle rated at 6,084. They changed from a full to semi float in 2001 on the Vans and during a tech seminar with Ford Factory suspension reps back in 2002 I questioned this change in even my 78 E-250 had a full float rear axle and their reply was "they have never had a documented failure in the higher rated semi float axles on any of their vehicles. So while the concept and added security of a full vs semi float is there, it's an added security that is not realistically needed.
You might disagree, but I now have 100K on my Van and my rear axle weight has consistantly been withing 200lb of the max rating on my rear axle when towing over 50K of those 100K miles.
