I agree, looks good.
The only thing I would double check is the door jamb label. It will list what your GVWR is, which it looks like you already know, but will also list what the Front GAWR and Rear GAWR is. These are the two numbers you should not exceed when loaded/hooked up.
Your FAW only went up by 20 lbs, so I seriously doubt you've exceeded anything there. Your RAW jumped up 1200 lbs, though.
Again, you're in a 2500 HD so you should be good. I just happened to have noticed you didn't mention those two numbers.
