You can usually count on approximately 40% of the tongue weight to be transferred off the rear axle if the hitch is set up properly. Half of that would get distributed back to the TVs front axle, the other half onto the TT. Only way to know how much for sure is to get it weighed, as all trucks, trailers and hitch set ups will behave differently.
Just to be clear, it is not 40% of tongue weight.
So using the OP's 800 pounds of TW as an example:
Dropping the tongue on the ball will add about 1100 pounds to the rear axle weight and remove 300 pounds from the front axle. Adding a WDH and adjusting such that the front axle is back to unhitched weight will cause the rear axle to increase about 650 pounds over unloaded and trailer axles increase by about 150 pounds. So 40% of 800 pound TW is not removed from the rear axle. About 40% of the added rear axle weight will. 60% of 1100 pounds = 650.
