A 2001 Expedition is more than likely going to have a 5 speed Allison which will be the limiting factor. It will not be a powerhouse but it will get you there. May also want to look at the front suspension as some of the Expeditions in that era came with a leaf spring front suspension which rode rather harsh. Friends had one and towed a jeep no problems and would have kept it if it wasn't for the front suspension. They loved the floor plan.
