There are people here that may not be comfortable with this but I would be. Especially sense you are well within your tire ratings. I basically run a little over on my ratings but not a whole bunch. With my boat in tow I run a few hundred pounds over my GVWR. But like I said I don't run 75 mph down the interstate, when fully loaded. I would think that rig would handle your load very well. The new Duramax's sense 2011 are a whole different world. I think your rear axle itself is rated at like 11k not sure though. I realize GVWR is about the brakes,transmission and the whole ball of wax not just your axle's or tires. I wouldn't run super high speed fully loaded, but that is JMHO. Obviously the best bet is to be under on all numbers.
