I read all about the EB towing UP mountains, but never hear the owners of said trucks talk about how they handle and slow down on the steep grades! Let's HEAR what the owners have to say!
Less engine braking than my 8.1lL with a 4.10. On one specific long downhill run I could hold my speed with the 8.1 but have to use the brakes a couple of times with the EcoBoost. I do not consider this a problem. I am impressed with the tow haul mode which applies engine braking effectively to complement braking on modest hills and through turns. I went from a Suburban 2500 and Prodigy 2 to the F150 with integrated braking and overall the braking is vastly better.
