Based on your factory white sticker you have a 145" wheelbase. It is either the supercab with the 2/3 rear doors and a 6' bed OR a supercrew with four full doors and a 5.5' bed based on the wheelbase.
Per the sticker you have 3.55 rear axle. You said you have the towing package. Actual door configuration (stated two different ways in the three threads) and engine are the remaining variables in order to use the Ford 2014 towing capacity chart. 4x4
Supercab 5.0L 6' bed. 7800# max towing 13500#GCWR
Supercrew 5.0L 5.5' bed 7700# max towing 13500#GCWR
Super cab 3.5 6' bed ecoboost 9700# max towing 14,400# GCWR
Supercrew 3.5 5.5' bed 9600# max towing 14,500# GCWR
7350# is your GVWR. When your truck is near its GVWR, after you subtract that from the GCWR (from the last listed) of 14500, that actually leaves you with 7150# of tow capacity left vice the 9600# from the same chart. So the ballpark estimates based on cargo capacity and tongue weights in this and the related threads were close
😉Knowing all these numbers and the ones on your factory stickers is good but best bet is to take your fully loaded truck to a set of scales to get the true weights being carried so you KNOW your remaining cargo capacity for tongue weight.
