Have you driven one and compared it to your Yukon XL?
From my signature, you can see I have the latest Suburban. Previously we had a 2012 Yukon XL and my impression is the interior is far better, but some of the fit and finish lacks what goes into a BMW. We never had a problem with squeak or rattles in the Yukon XL and it had over 125k miles when we replaced it with the Suburban.
I have driven several Expeditions as rentals with work. My impression is that the Expedition has very sensitive steering and it felt like I was constantly correcting the steering. This got very fatiguing on a 2000 mile road trip. At the end of that trip I couldn’t wait to turn that one in. The last one I rented was a 2019 Max in January of this year. Still has the same steering feeling to me. Honestly, I was underwhelmed with the Ecoboost in it. I guess I was expecting more apparent superiority over my 5.3L. I have also driven F150’s with the Ecoboost that performed better in my opinion. I don’t know how the ride that I experience would do towing. Coworkers who have also driven the Expedition have said the same thing.
