Well, the tires look like they will take the load so the only things that are off are the GVWR and the rear axle certification.
I run about 400 lbs. over on my GVWR on my dually, and way over on my GCWR. But I don't really concern myself with GCWR since that seems to be mostly a function of warranty and gearing.
Some guys totally ignore the GVWR and only worry if you exceed your GRAR(Gross Rear Axle Rating). I think I would be a bit uncomfortable being nearly a ton over my GVWR (probably by the time you add your toys).
Personally I think it's a bit too far over the GVWR, but that's just me. You'll find people who will vociferously disagree. So it just boils down to how you feel about it. You know you're overweight, now how do you deal with it.
