No it should’ve caused a fault on the build sheet. With you wanting 4x4 it should automatically drop the tow package. Is the FX4 is 4x4 which comes with a better motor, transmission, gear ratio, upgraded cooling system and suspension. Your also paying for extra plastic on the FX4 unless they finally went with metal skid plates. I have a FX4 F150 and everyone gets on me saying that it’s not able to tow more than 6500. My dump trailer empty weighs close to 2 ton and I’ve pulled 8 tons without a problem. I’ve even hauled 10 tons of trailer and equipment through the mountains and only had one problem. Which was the last turn 10 mins away from the office and it was a really steep hill. I would’ve been fine if someone would’ve pulled out in front of me going up the hill
