Definitely interested in what you uncover. I want to get a 157" Sport Lariat PB. Probably won't get the max tow if it hurts my payload.. I have a 26" camper I will tow with it.It gets weirder... There are now TWO different flavors I have seen of the 7050# GVWR with FX4 and max tow: One where the axle ratings are 3600+3800, and one (like the image I show) where they are 3600+4150. BOTH are listed as 7050# GVWR.
To make things weirder, the 157" wheelbase gets a 3600+4150 but gets a bump in GVWR to 7150#. The Powerboost FX4 maxtow gets 3900+4150 and gets a full 7350# GVWR.
So if I were taking delivery of an EB maxtow and my rear axle is only 3800 I would question why I did not get the better axle. I think I will bump my GAWR thread and see if more owners can share white stickers.
