To the earlier threads, GVWR also take in to consideration the ability to stop safely. Anyone can take an F250 and throw bags and a bigger spring pack in there to increase your hauling capacity, but if you can't stop you will likely kill someone. Larger trucks have better brake packages. Additional axles on trailers add more braking wheels along with each axle. Overloading your truck and hard braking will lend itself to a phenomenon called Brake Fading. Snowking can correct me here, but I think it comes from the brakes heating up to a point where the surface of the brake pads become slick and don't grab the drum. That much heat can also throw your drums out of round so you have even less braking power. This is why larger trailers have electric brakes and more axles.

That is pretty correct about brake fade, and a very good point. I assume though Ford took that into consideration when listing the GVW of a truck (at least I hope) Pads will become slick and wear away rapidly (literally burning off) with brake fade, the drum expands and cracks, then the **** hits the fan
On a side note I know Fullcrew has added a aftermarket Jake brake to his truck which helps alot, when using my Engine brake in my fullsize semi I rarely use my foot brake anymore.

Ryan, I used an LT9000 for my road test. Unfortunately, they sent me with a really short tandem axle flatbed, so that backing part was a bit tougher. I had hoped for the tridem end dump. So much easier to back. Yup, I did the walkaround. Scary part about that, is the lady doing the examining had been a travelling dental hygienist that came to the area schools when I was in Elementary school. She'd never even moved a semi, let alone driven one. Everything straight from the book

As for the braking, yeah, that designed into the vehicle based on the desired GVW the manufacturer is going for.
About the exhaust brake, I love it. May just be the best $7 I spent on mods.
On the 7.3's the exhaust back pressure valve can be converted into an exhaust brake by wiring in a switch and a separate 112v powers source. Works best at higher RPM. Not quite as good as an aftermarket one, but still gets the job done and VERY little cost.

An exhaust brake on a semi is about the most useful thing ever.
If I did alot of towing I would install one in a second on my pickup truck.
Regarding the break fading, when I lived in BC I heard lots of stories about guys riding their brakes coming down the Coq, and having to get a complete brake job in Hope!
Also with larger trailers you can overload a set of axles and get a fine, and not have your whole truck overloaded. (not sure if that was mentioned or not)
