I don't have exhaust brake, but with the "Selec-shift" transmission I can keep my #7500 trailer under 50 mph on a 10 mile 5% descent...without applying the brakes. With the right technique I really don't see braking an issue in this case.
The only issue I see is the 3.55s
I think the original issue was trailer braking. Your trailer brakes are your secondary brakes, not primary. Never set them stronger than your TV brakes unless you want to see your trailer pass you on a wet curve.
Regardless of the specks, if you put the 1500 and 2500 HD Duramax side by side, the 2500 HD brakes are larger as is the drivetrain. I did this when I bought my 2500HD to see if there was a difference. I do believe the callipers are larger too.
I was weighing whether to buy a 1500 with tow pac or the 2500HD Duramax/Allison. No comparison. Huge difference especially in the drive train. Rear end is 3.73. In tow mode with exhaust brake on, braking is never a problem. It figures it out without my input. The Allison 1000 transmission handles it all.
