I figured the bumper and fuel tank had little to with Ford's additional advertised 500 lbs of 5th wheel towing capacity (10,300 vs 10,800) and 2,600 lbs of GCWR for a 5.0L/3.73. I believe @Atlee has the decoder ring. I went to the dealership on Sunday and every '23 F150 with the regular tow package, or no tow package, had the single leaf springs. The trucks with the max tow packages had the thicker, double leaf springs. This solidified my decision to proceed with my custom order instead of taking the available truck with a regular tow package.

What's funny to me is that every window sticker with the regular tow package I looked at on Sunday, included the 3.73 axle upgrade for an additional $570 and extended range fuel tank for $445. The axle upgrade and 36 gal tank are included in the max tow package and their addition to those builds made the regular tow packages $125 more than a max tow package. And the 3.73 with the 3.5L GDTI reduced the max 5th wheel towing capacity by 2,100 lbs, compared to the standard 3.31 or cheaper upgrade 3.55 axles. Maybe some folks prefer the ride of the single leafs over the stiffer ones, more than maximizing towing capacity.
