It appears that the hybrid is good for 12,700lbs and the 14,000lbs rating is for the non-hybrid drive train.
Hybrid, 12,700lbsStandard truck 14,000lbsUntil I see it in the towing handbook I am going to take the numbers with a grain of salt.
The HO version of the 3.5 used in the Raptor and Limited is missing from the charts but the standard version is up to 400hp while the hybrid is at 430hp. Presumably for just a short burst though with only a 1.5kwh battery. I would like to see it with at least a 10kwh battery.
