I think your worst case scenario is that 100% of the cabover weight is placed on the front axle. Without weighing you don't know how much capacity you have. Weigh with full load and passengers.

If I am reading the OPS post correctly he is well aware of his overall weight capacity. Which is huge in the Redhawk because it is not loaded down with much of the equipment a Greyhawk carries. I don't know the exact number but I believe it is well over 2000lbs. His concern is wether or not he can load that weight safely into the Cabover bunk.
I don't think his concern is how much weight he is placing on the front axel. My interpretation of his post was that the dilemma is wether or not he could potentially tear the cabover off while driving. The lever is relevant to the cabover itself and the fulcrum point is where the cabover has been connected to the body of the house. The cabover on a Redhawk/Greyhawk has no contact with the roof of the truck so the entire weight of the cabover and it's contents pulls downward over that fulcrum point making the entire unit a 4 foot lever. Hence the reason it has a 750lb weight limit when at rest.
All that being said, Grumpy is right that many of the cabovers have replaced the bunk with heavy entertainment units at the front. Probably about 200lbs of lumber and TV. So most items the OP is likely to put up there are going to be inconsequential. The one difference is that the entertainment unit is completely stable within the cabover so the force it creates is a constant. Loose items that can bounce will create a variable force upon the lever. Me, I am a bit anal, I would still put the heaviest stuff to the rear of the cabover
