---What Ron is quoting is for the 1500 series towing over 7,000 pounds. 50% is the required FALR for those models. Per GM
In one place the manual says, for a 1500-series truck, a WDH must be used if the tongue weight exceeds 800#.
This implies that a trailer with a TW% of 15%, and a weight greater than 5333#, must use a WDH.
It also implies that a trailer with a TW% of 10%, and a weight less than 8000#, does not need a WDH.
In another place the manual says, for a 1500-series truck, a WDH must be used if the trailer weight exceeds 7000#, a WDH is required and the "weight distribution" (assumed to mean FALR) should be 50%.
This implies that a trailer with a TW% of 15%, and a tongue weight less than 1050#, does not need a WDH.
It also implies that a trailer with a TW% of 10%, and a tongue weight greater than 700#, must use a WDH.
Perhaps what the recent Silverado Owners Manuals are saying to 1500-series owners is:
if your tongue weight exceeds 800#
OR
if your trailer weight exceeds 7000#,
then you must use a WDH.
And, whether required to or not, if you do use a WDH, it should be adjusted to eliminate approximately 50% of the front-end rise (50% FALR).
For Silverado 1500s prior to the 2013 MY, the WDH-adjustment specification call for returning the front end to the unhitched height (100% FALR).
