I just ordered one last week. Looked around a little for feedback on the 4.10 v 3.73 but didn’t find much.
I live in the flatlands and will mostly tow in areas I’m not climbing a lot of hills so I don’t think I’ll have any issues with the 3.73.
BTW they told me 10-12 weeks for it to arrive, which would mean around Memorial Day. With all the supply line issues going in these days, I figure on not counting on it being here by then, and it may end up coming more like July. Ordered vehicles do get priority on the schedule, and automakers are shifting items in short supply like semiconductors to their high margin products like trucks, so maybe I’ll get lucky and it will be here when estimated. But keep that in mind if you need your new truck by a certain time!
