Anybody else using one of these to tow? We are complete newbies, so forgive my lack of knowledge. I bought a 2021 F150 with all the tow packages, including the new tow-assist module (replacing wha...

A 15,000 lb rig with 70sq ft of frontal area needs about 115hp to go 60 mph. increase that to 90sq ft, you need about 135hp to go 60 mph. SAME HP as a 25000 lb rig with 70 sq ft of frontal area. EA additional 3 sq ft of FA will need the same HP increase as just adding 1000 lbs of wt. These numbers mind you can vary by plus or minus 30% depending upon the aerodynamics of a given rig.
The other not given in the tow ratings, is you can tow over the frontal area sq ft. BUT, what is NOT given, is the wt reduction for going over. or if under 80sqft to say 60, what addional wt can you pull. Reality is, for how good some of you think the new tow rating specs are, there are MANY holes in it, this being one.
Or if you want to pull over a 12% grade, how much do you have to reduce tow ratings by too. That is all you have to be able to pull, granted 5 times in low and reverse and not over heat. But if you are like me, and pull local roads in the 15-20% relm frequently, will the rig do so?
FULL reality is, the tow ratings generally speaking, WILL NOT work for many of us, unless we can truly fall with in ALL perimeters of the spec. Most of us tow outside the perimeters! I know I do quite frequently. Enough to not trust them.
