What are the differences between a E150 and an E250. Do they use the same rear end with just heavier springs on the 3/4 ton, or is there more to it?
I'd say I'm overloaded with the 1/2 ton springs and thought I might take the van to a spring shop and have more leafs added to beef up the springs. I've done this with previous vans.
The 150s and 250s have completely different rear axles. The 150 is a simple 8.8" unit used in many Ford cars and trucks.
The 250 uses a big full floater, typically a Dana.
I use add-a-leaf helper springs on mine. You can buy any number of these from JC Whitney or off the shelf at a trailer supply company or Camper dealer.

Hi there:
The E150 of recent years has the 8.8" Ford rear axle (my '02 has the 31 spline axles) and 5 lug wheels with 15" car type XL tires (switched to 16 inch wheels circa '05 maybe, but with car type tires still). The E250 has a Dana 60 rear axle, much stronger and with much greater weight capacity, and with 8 lug wheels and truck tires. Larger brakes, etc, and I believe the axle is spaced up a bit higher.
I am sure that many E150's have been overloaded throughout history, but wouldn't suggest much of an overload on a constant basis, especially with stock tires.
As of either 2007 or 2008, the E150 basically became an E250 with 8 lug wheels and a much larger capacity. So the new ones will naturally take a lot more weight.
Careful with overloading any vehicle. I'd worry most about tires and brakes.
