The OP asked for our opinions and he's getting them, nobody "hating" anything.

 

Certainly no hate here, not even for those bull-doging guys ... just as long as they don't truck-nap mine and try to bull-dog it in some evil lab under a full moon!

 

Interesting. Ya gotta make everything about you? If I was referring to you and your fragile ego I would’ve quoted you. I get it, you don’t agree with my opinion. That’s gonna happen a lot in this life. Get over it, or don’t.

 

Damn, didn't mean to hit a nerve. LOL

 

Do you have a pic of your F150 while towing? How does it look. If it looks relatively level than leave it alone. Done ! If you still have a slight Rake, then go for a 1 or 1.5" level.
I never tow anything, went with 2" suspension level. Just haul every now and then ( 400-700lbs., rare occasion 800-1200 lbs. )
