If 2000 lbs sets it on the overloads, they must be an integral part of the suspension, not just a stopping point. Some overloads that I've seen aren't much more than bump stops in function. Besides, I have a friend that hauls 20,000 lbs of big round bales around his families' farm(2000 acres) in his 03 2500 without squating much AT ALL. I've seen it. The distance between the rear tires and the bed only decreases by two inches or less. And that's WITHOUT overloads!
Regardless, I still got the 3500 srw. My friend says that if he buys a new truck, he also would buy a 3500 srw.
Wardog, I believe when I shopped the price difference between the 3500 and the 2500 set up the same way, the 2500 is about $800 less than the 3500. The overload springs, the overload spring stops, and the redneck lights are the only difference between the two.
