The thing is with the Titan xd 11,050lbs, is its tow rating. With the f150 and Chevy tow ratings that were stated in this video are for the bare bones, non 4wheel drive model. You will not find an f150 with 4 wheel drive, crew cab, sunroof, etc… with 14,000lbs. The stated f150 and Silverado tow ratings in this video is very misleading. Also, Titan xd has an axle from American Axle. Not Dana axle.
You have payload and towing capacity mixed up. The towing capacity is based upon a Titan XD but then you talk about payload which is part of the regular Titan non XD
