I don't know from Expy's, but based on the numbers of the newer 150's in comparison to mine, I too sometimes have the thought balloon appear above my head "Hmmm....really?"
Shorter wheelbase (145" compared to 163"), taller tires (20" compared to 17") and lighter capacity wheels (and axles?), payloads generally lower by 500-700 lbs (mine is 2200lb compared to 1500-1700) and still OEM whimpy receiver that flexes badly under tongue weights near max of 1150, and yet because of the HP and trans increases, they are rated to tow more than my 9300 lbs and 15,300 combined with the 4.10 and four speed? Granted, I'd love an extra 30 HP and one more practical gear (the last two or OD's) but I don't see the difference covering the gap, especially when the payload is such a big player. I'd love to hitch my 8K to one and see for myself. Other than the power of an Ecoboost in the mix, not sure there'd be a whole lot of difference. At least not enough to give to nod to higher tow ratings. It'd be interesting to see "seat-of-the-pants" comparisons.
