I have the 3.5EB w/ 10speed in my supercrew. It flat out hauls a** and I drive 70-75mph, commute 54miles round trip for work and average 18.1mpg w/ the 6” lift and 35” MT tires. It too is our family travel vehicle as it rides better than my wife’s GC trailhawk w/ air suspension and my wrangler sits in the garage bc my truck ride is so nice.I have a buddy that has a 6" lift on his F150. I like the look but just can't pull the trigger on our F150 since it's our road trip vehicle. The 2.7EB with 10AT does great for road trips at stock height, but the MPG hit has prevented me from pulling the trigger on a lift. We talked about lifting our F150 around 3" but will probably settle for a 2.5" level kit (if we do anything to it) and then go to town with the Bronco and Sasquatch since we won't be using the Bronco for any long drives.
Steps do help!
